Yes, it seems more logical for the capability to be TRANSIT, because
extensions might offer more transit commands (TAKETHIS, for example).

Moreover, you MAY provide the IHAVE command even when in READER mode, but
does this make you a transit/general server (i.e. do you advertise the
TRANSIT/IHAVE capability)? I would have thought not (certainly not
TRANSIT) because the exact semantics of IHAVE may be slightly different
when in READER mode, and you wouldn't expect TAKETHIS suddenly to appear
as well.

Indeed.

Yes. If we no longer have OVER and HDR as extensions, then we have lost
the ability to say "If you provide this extension, then you MUST provide
BOTH of the following commands". I don't think we ever intended to lose
the ability to say that.
