As gnus-summary-save-parts (X m) is invoked on the article, it could
offer completion based on what mime parts are present in the article.
Thanks.

I've attached a "dumb" version of what that could look like.
Two notes:
1. This would obsolete `gnus-summary-save-parts-default-mime'.
Personally I think that's totally fine: between completion and
a history variable, I don't see any use for a default
value.
2. If we go this route, it would be nice to extend it so that, for
instance, if _any_ image/ media types are present, we also manually
add a "image/*" entry to the completion collection. Or for maximum
OCD, only add that "image/*" entry if there are more than one image/
type handles present. Matches are not required, so you could always
just type in your own regexp, anyway.
Let's see if anyone has any comments.

Sounds like a good idea, but is probably not practical, since it would
mean that Gnus would have to retrieve all the process-marked articles
first to do the prompting. If there's only a single article in the
list, then it would be fine.

I think that variable is useful. In practice, people are interested in
saving only certain types (images for some, pdfs for others), and being
able to hit RET to do just that is nice. This is particularly the case
when using the command over a large set of messages (typically, all the
messages in the summary buffer).

Adding foo/* variants if several different foo/s are in there would be nice.

This only deals with types in the current article? The message may not
even be selected, so (in addition to not working on sets of articles),
it would not work if the user hasn't selected an article?

Well I did say it was a "dumb" version :)
I hadn't considered the case of multiple articles. Just for the sake of
argument: if we're expecting to save parts from some of the
process-marked articles, aren't we going to need to fetch them all,
anyway?

I still think that combining "the mimetype we saved last time" with
"what's actually present and saveable" mostly obviates any generally
preferred mimetype. But I don't feel strongly about this at all, and
there's no great need to remove that variable.

Right, like I said this was more a proof of concept than a working
solution. If you think there's a practical improvement to be made in
here, I'd be happy to work on it.

We are, but unless you have backlog (etc) switched on, Gnus will then
fetch everything twice.

If there's only one article in the selection, then ensuring that it's
fetched should be sufficient before you look at the MIME handles.

Bleagh, no time for coding... Anyway, I played with this, and the amount
of (duplicate) code that would be required to check if we're only
dealing with one article, and whether the article is fetched or not,
sort of makes it not quite worth the effort.
Unless we're interested in factoring out the tests in
`gnus-summary-select-article' into a new function like
'gnus-summary-current-article-fetched-p', which could be used in both
places. That might make it easier.

I think so, too.
But offering completion based on just the first article is better than
nothing, so I applied your patch (with some slight changes) to Emacs 28.
