LaTeX packaging policy

[Josselin Poiret]

Hi everyone,

While using a bit of LaTeX recently, I've noticed some packages don't
work "out-of-the-box", at least on LuaLaTeX, and need some additional
propagated inputs.  Examples would be babel-french needing scalefnt,
fontspec needing luaotfload, or hyperref needing stringenc.  Is there
any established policy for what propagated-inputs need to be included in
package definitions?  Should we add some LaTeX specific packaging
guidelines in the manual, like for Python or Rust (the former is
outdated by the way, mentioning Python 2 packages).

I can work on those if there's some sort of consensus, but just need
some advice from more experienced LaTeX packagers.

Best,
