Probably other people have a more substantial answer, but let's try... Thank you, Simon, it did bring some light. I was thinking about this problem not from an end-user point of view but as a (potential) developer of one of these libraries. Firstly, Sage is based on an object oriented

Great! Welcome! What sort of library are you thinking of? Magnus - a package for finitely presented groups, may be. It's a possibility. If there was a library that only worked for sparse matrices, but the user wanted to use a function on a dense matrix, I don't see any way around

Why not to do such translations (from a polynomial to a polynomial) transparently to the user? The section you looked at is actually a pretty ugly example indeed and with the current Sage getting objects from one system to another is much more elegant. I see, is it described somewhere? --
