"Styx featuring Foreigner" is exactly what will appear as you create the joint artist
Right, I didn't claim otherwise
and then with using the plus sign you add (hence the plus) the individual performers for this joint performer (sorry if you take objection in 'members', we do not need to stick to that wording, it's a pointless discussion about a nomenclature, nothing else).
I obviously know what the "+ Artist" does now. The button could read "Hot Pizza" and I would now know what it does. The point I made was that "+" was the root cause of my initial confusion and will likely result in future confusion for others. Since I prefer not to complain about a word or phrase without suggesting an alternative, I so suggested with "Sub-Artist". I don't claim that this is the best alternative, just better.
Terms of art are important for clarification and precision for SHS. These include "work", "performance" and "release". I simply pointed out that a "member" of a band is different than a constituent "artist" of a joint "performance". This all makes terms of art not pointless nomenclature.
Not sure if such effort is worth it. Is this one of the submissions to which you refer?

If so, the obvious answer is to just submit one cover from the release and just reference the others. Many editors prefer that anyway....
Well, for me it would be beneficial as doing what you suggest (and what I actually do as explained above) is taking away functionality on the page of the work as the performing artists are not linked, whereas they are linked if you actually add them using the correct process.
It's a cost vs. benefit. What are the costs of implementing possibly complex coding to handle the relative few repeated joint performers? There have been "backlog" concerns over the increasing number of unprocessed submissions, a concern somewhat mitigated by one cover submitted per release policy. Lastly, submitting under one of the joint performers and noting the other performing artists and the additional covered works does result in search returns.
Additional observations:
a) Auto-filling the first common name field from the performing artist field is an unnecessary error/typo trap. It should pop-up blank like the second et. seq. fields do.
b) Due to all the variations, getting the internal hyperlinks automatically correct seems like an infeasible if not impossible goal:
A featuring B & C
A + B featuring C
A vs B & C
