Do not hint deprecation and future removal with "still" and "for
now", before seeing a concensus that it should be deprecated and
removed.

The new thing, <recursively>, deserves some explanation.  What are
the acceptable values (yes/no? spatial/time/both? infinitely/limited?)
and what do these values mean?

Why is this limited to only <blob> and <commit>?

There isn't a fundamental reason why I shouldn't be able to say
"v2.32.0" instead of ebf3c04b262aa27fbb97f8a0156c2347fecafafb (or
"v2.32.0~0") to say "I want anything reachable from v2.32.0 (in
other words, that version and everything before it)", is there?

For that matter, "everything reachable from this tree object" may
also be a reasonable way to specify which set of objects are
offloaded to an out-of-band URI.

Thanks.
