It's actually not even 1-based indexing. Because Lua doesn't actually have arrays.
It only has bool/string/number primitives, an associate hashmap object that it calls a 'table,' and a hacky add-on on top of that which mix-and-matches features of Symbol and Proxy in JS - which it refers to as meta-tables.
It doesn't actually have arrays. Arrays are just a convention expressed through part of its standard library, for iterating over numeric looking table keys. The standard library functions expect iteration to start at 1, but it doesn't have to. It could start at 0 as well. Or at 5. Or at 42. Or, if you're a particularly crafty fucker publishing code modules as a third-party, who wants to fuck with people: -1.

It'a pretty meh for config; it's fine either way.
But as a scriptable interface, it's leagues better than the "run sequential ex commands to change your buffer" language that is Vimscript.
t. tried writing plugins in pure Vimscript and got frustrated at how autoload imposes a strict directory structure on you with terrible cross-submodule support

Can you really see no use for this?
I guess it requires having 115 IQ at minimum to realize the numeric value associated with a data point along an axis (something you'd use a list data structure like an array for) isn't always the same value as the data point's position relative to the list in the program's memory. But you are so cnile that your brain can't even separate those two concepts at all, even though they're very different things... I feel bad for you, it's like having a mental illness.

1-based indices actually have a property that starts at 0, that being the length. If I have 5 apples, I label them 1, 2, 3, 4, and 5, but if I don't have any apples, I have 0 apples (aka the length of the list is 0). So the number 0 isn't wasted in the case of a 1-based array.
Whether it makes sense to start from 0 depends on the question you're asking, for example if you ask "how far away from me is the closest object?" a valid answer would be that it's 0 meters away from you. But if you ask how many objects there are, notice there HAS to be at least 1 object, otherwise the question of how far away the closest object is doesn't make any sense.
The reason you index from 0 in C is because indexing an array with value n is asking "what is the nth repetition of this object?" which is closer to the question of distance. arr[4] in C is asking "give me the 4th repeated value" which happens to be the 5th value. The reason it's framed this way is because it's how you think about memory allocation (an array of type t and length n allocates sizeof(t)*n memory, and the index is a multiplication of sizeof(t)) but it's totally arbitrary.

You can differentiate the two things in your code, but apparently you don't realize that means you can turn it into an abstraction without losing anything.
Just like when typing a string, you type "hello world" instead of "104 101 108 108 111 32 119 111 114 108 100".

I don't think you are fully committed to this logic unless you use ascii tables to write out strings and write 0 and 1 instead of true and false. In fact, you are probably stupid if you even so much as use indices, every value above 0 is an abstraction so it doesn't reflect the real data. You should be casting array+size+index to a pointer and dereferencing it directly, otherwise you're too stupid to understand pointers.

you get rid of annoying conversion steps where you have to shift indices and can instead just insert directly at that index
you also reduce the chances of off by one errors and can use your mental energy on other stuff
