Short answer: Yes<br>

There's a few problems here:<br>

? That is what they can be used for. See the site relation as an
example. <br>

<br>
This reinforces my point. Site is repeatedly used to form
unnecessary collections of things (such as braces of bus stops, one
on each side of the road which already share the same name:
<a class="moz-txt-link-freetext" href="https://www.openstreetmap.org/relation/2726555">https://www.openstreetmap.org/relation/2726555</a>)<br>
<br>
...or by people who are unaware OSM is geospatially aware. Note the
'site' example given on the wiki:
"Relation to group elements of a site such as a school together.".
If the school has a amenity=school polygon boundary, which it
should, everything within it is a part of that school.<br>
<br>
It wouldn't be so bad if people didn't give up half way through
creating them. <br>

Clarification: It shouldn't be a part of the multipolgon relation.
It should still be a polygon. <br>

No. They can be used to collect a series of outer ways to form the
boundary of a feature e.g. an administration boundary usually
shares ways with adjacent administrations.<br>

Clarification: I was referring to specific examples of river MP's to
include islets. It makes it much easier to maintain if the relations
are kept as small as possible around any inners. If the MPs are
large, some contributors mistake them as untagged ways and add
duplicating tags to them. To help avoid this confusion I add a note
tag to the way: <a class="moz-txt-link-freetext" href="https://www.openstreetmap.org/way/431275464">https://www.openstreetmap.org/way/431275464</a><br>
