An other option would be to create a 'special' libxine1-vis package,
which has libxine recompiled with optimised libraries.

That would be and ideal solution, however I'm not sure whether it is
easily achievable. From a cursory look at the source of the component
containing the sparc64-specific assembler I got an impression that it just
does not ship any generic unoptimized code. I would be glad to be proven
wrong on that, but to me it looked like making it work on sparc32 required
a significant effort.

If the decision is that it is okay to include vis depending code for
ffmpeg and related packages, then I think we should have this documented
in the Developers Reference, if not, in Debian Policy.

I don't think it's such a big deal, but at the moment it's up to release team to decide whether such packages are considered RC-buggy.
