Makes sense. The implementation looks pretty sensible. One observation:

The OBJ_* constants are a contiguous set between COMMIT and TAG, and it
has to remain this way (because we use them to decipher the type fields
in pack files). But I don't think we've generally baked that assumption
into the code in this way.
Writing it out long-hand would be something like:
if (t != OBJ_COMMIT)
filter_bitmap_exclude_type(bitmap_git, tip_objects, to_filter, OBJ_COMMIT);
if (t != OBJ_TREE)
filter_bitmap_exclude_type(bitmap_git, tip_objects, to_filter, OBJ_TREE);
and so on, which isn't too bad. I dunno. That may be overly picky.
