Not sure why you think the problem with ipairs was magic, it was just
deemed (for a little while at least) unnecessary.

_ENV is a core construct of Lua, something you're going to have to
understand eventually anyway, it's not a restrictive single purpose
function replaceable with ~3 lines of trivial Lua in your module file
where the latter also provides more useful and obvious semantics.

I'd also note that it's not necessary or beneficial to touch _ENV at
all in your module unless you're doing something weird.
