ctan experience is that one gets essentially no response.

but surely, if texlive is a part of debian tex strategy, confusion is
engendered if there's no clear split between free and nonfree, in
fwiw, we have had to give up the ctan nonfree tree; we did a small
amount of systematic work on it, and realised that the two would end
up roughly equal sizes: we simply don't have that amount of processing

i mark them licence 'unknown' -- my assumption is that such packages
should be regarded as nonfree

i mark them licence 'pd' -- i really have no clear idea how such a
thing might be treated legally, but we do have that implicit
permission to distribute.

i tend to let such packages stand, provided they have the standard
rubric "or any later version, at your convenience".
another one that is bothering me is:
- claiming a licence that requires source distribution, but not
i'm searching such things out, and marking them unknown (see above),
hence nonfree (in my view).

if the documentation is a derived product (as is often the case with
latex and context things), this isn't an issue (or is it?).
i've not investigated the licences applied to documentation, in fact.
note, when i say above "i do <x> to a package", i'm referring to what
i write in the tex catalogue.
