You have no idea what 90% of their users are using. A lot of them aren't using LLVM or GCC. I'm pretty sure Roblox and WoW, for example, aren't normally compiled with LLVM or GCC. Whether those two games account for 99% of Lua's users or 0.001% depends on how you count, but no matter how you count, you have no idea.

Roblox accounts for 0% of stock Lua users, they run Luau. And many uses of Lua you come up with will be using LuaJIT or pinned to an older, possibly forked, Lua release.

I'm not agreeing with the comment you replied to, just nitpicking.
