(I'm going through old bug reports that unfortunately got no response at
the time.)

vc-annotate seems to work quite fast for me (even in huge files that
have decades-long histories, as in Emacs), so I'm not sure adding
support for incremental annotation would be worth it.

But perhaps changing the function to only work on the narrowed portion
of the buffer would be nice?  That way you could `C-x n d C-x v g' (for
instance) and get a very snappy annotation of just the current function,
for instance.
