So if I understand you correctly, you would be ok with fixing the
dependencies of rocks that are proven to break for Lua 5.2 -- some form
of faithful dependency: If nobody complains we assume the rocks are
compatible with the latest Lua version.
That would already help a lot to get the repository to a state where it
can be used with Lua 5.2.

Most C bindings break. Lua-only modules should be ok, unless they use
setfenv.

When you say "in my experience", do you mean experience with rocks, or
some other version management system? Because in case of rocks there is
not much opportunity to get this impression:

Only 36 rockspecs specify that they don't run on Lua 5.2 (and for the
listed yaml, lfs, luasocket, and lbci versions I *know* this to be true).
