I think a first step would be removing the "un" prefix from
"undocumented". :-)

Usually we have sections in egg documentation about assumptions, known
bugs, limitations, caveats etc.  The documentation is in our wiki.
Everyone can make contributions to improve the quality of egg
documentation, including mentioning caveats.

Ideally bugs should be fixed, of course.  When they are discovered, they
should be at least reported (e.g., or whatever
issue tracker egg authors use).

I'm not completely sure I understand what you mean by "block list".  I
think the best we can do is document issues, really, and leave it up to
users to decide whether the issues are relevant for their use cases or

All the best.
