(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

This is still the case in Emacs 29, but since basically git won, it'll
probably take an SVN enthusiast to get this fixed.

Adding -v indeed gives the time:

     1      larsi 2022-05-05 13:46:34 +0200 (Thu, 05 May 2022) This is foo.
     2      larsi 2022-05-05 13:46:41 +0200 (Thu, 05 May 2022) Yes.

But that's too massive to display, so vc-svn-annotate-command would have
to implement a filter to reformat that in a more sensible way.  It
shouldn't be a lot of work -- the person implementing this could look
at, say, vc-cvs-annotate-command as a model for how to write the filter.
