It is more intentional than it is by accident that we don't.

We would really think hard to avoid breaking when introducing new
options whose long name could begin with "v" or "q" to avoid
breaking "-v" and "-q" that are common across commands, but it is
entirely plausible that we want to add a new option whose name
begins with "re", and at that point, "-r" or "--re" stop being the
unique short form to trigger "git pull --rebase".

If somebody figures out "git pull --reba" or even "git pull -r"
works by accident _today_ and gets used to using it, that is fine,
but we do not want to guarantee the future.  We reserve the right to
introduce "git pull --repurpose" in a later version of Git, and make
"git pull --re" error out for ambiguity, breaking fingers of such
people who relied on "used to be but no longer" unique

See above.
