I would find that ... surprising.  (I have tended to rebuild FreeBSD
head & stable (head - 1, usually; lately, also head - 2) daily on
at least a couple of machines for the past several years, one of
which is the laptop I use for day-to-day "stuff" -- so I do have
"some experience" using "make buildworld" & friends.)

I generally do that, yes.  And I am unaware of any problems the practice
may have caused.

That said, there was an occasion when a "git fetch" from one of the
mirrors choked & died; since then, I have taken to running a weekly
process via cron that does a "git maintenance run" followed by a "git
gc" in each of my git repositories.  No issues since starting that.

Peace,
