I'm not sure the current behavior you described is a bug.  You seem to
be so confident it is that you haven't even provide an explanation why
you think so, and a naïve reading of the doc string doesn't make that
obvious (e.g., "if needed" could cover item 1).  In general, when
transient-mark-mode is off, Emacs behaves differently than when it's
on, and that's by design.

So could you please provide a more detailed explanation why you think
these are bugs?

Thanks.
