You don't want to arrest them, rather than charge a penalty fare. So will
there be a regime where the gripper takes a "swipe" from every such card
offered, and then a post-processing of the penalty for all those where the
card was either not swiped in originally, or the swipe-in was not properly
registered?

Given that this is based upon wireless technology, there must be some scope
for this information getting lost.

I'd say it's as acceptable (or not) as being found not to have, as the
stickers say, a validated Oyster card. On the bus at least, it is IMO
very difficult to claim that you didn't know whether your card had
been accepted.

I can't believe that retrospectively fining people because the gripper says
that you were on the train but your bank account details don't show that you
have paid, is going to stand up to expert court scrutiny.

Well, it's not really a fine. It's a charge for not being able to
demonstrate that you've done the right thing, as unfair as you might
think that is.
