Call that paragraph ¶ 2.

As I thought, this observation contradicts the first thought expressed
in your Tue, 27 Oct 2020 20:43:52 +0000 post (the last paragraph of
quote below). I presume that although mounting is disallowed for   mount -a
(by noauto), your automounter is not constrained in this way.

Isn't that just what you answered in ¶ 2 above?

I guess your answer lies there then. AFAICT usbmount hasn't been
included in the last two stable distributions (stretch and buster).
I've never used it. I assume there are others here for which this
all works. (I've left it a day before replying.) I can't work out
where your questions are leading, and whether you have a problem
to solve (besides having flaky hardware).
