Why the /lua/ subdirectory?

Ran into the snag that require('lazy').setup('plugins') wants lua/plugins.lua, not plugins.lua

I've been looking up and down the neovim docs and lazy's source code but can't decipher why.

require('plugins') works fine and I don't really see lazy messing with package.path or runtimepath very much, so why does it necessitate the lua subdirectory? Just curious, the lua module system in neovim is taking some time getting used to.

Actually, is it because the require('plugins') call happens inside of ~/.local/share/nvim/lazy/lazy.nvim, so the ./?.lua path applies to there, not ~/.config/nvim? And instead you're intended to use runtimepath, which searches the /lua/ subdirectory?

The /lua directory is required by Neovim
