I'm not sure I agree. Lockless writes are actually fine for the original
use case of --no-optional-locks (which is a process for the same user
that just happens to run in the background). I can buy the distinction
between that and "--read-only" as premature optimization, though, since
it's not common for most operations to do non-locking writes (pretty
much object writes are the only thing, and most "semantically read-only"
operations like status or diff do not write any objects).
So there's very little lost by people in the first boat saying
"--read-only".
