(1) Am I right that this situation is unhelpful and potentially trouble?
(2) Would it be helpful if I removed the two extra nodes from the way? (

My guess is that these extra nodes have been created while people are
editing, and join other ways to the town lines. While understandable, I
see this as an error.
Yes, it's likely to be the case there that nodes were joined to the town
lines while editing, but if the item doesn't define a border (like the
midline of a river or something) then it shouldn't be a part of the border.
But, separately from that case, there is a school of thought that it can
be helpful to add some additional nodes on very long straight segments.
The API (or some of the APIs?) for downloading a bounding box I think
will only include a way in it if that way has at least one node within
the requested bounding box. So some people like there being a node every
so many miles/kilometers even if the way would still be in the same
place without them. I'm not going to take a position on whether or not
such is "correct", just saying that you might see it in some places
where it's intentional too.
I haven't been doing much OSM work recently, and I wanted to check before
proceeding. Is this a good list to ask this sort of elementary question?
I think so. Apparently some people think forums are better, but I
disagree.
This list is as good a place as any. You may find more people on the
forums, or the OSM US Slack <https://slack.openstreetmap.us/>. But there
are still some of us who are very comfortable with email, yes, and
hopefully enough of us to make a discussion interesting and helpful.
