"Part of" classical work in soundtrack?

I have noticed that two of the movements in the Faure Reqquiem (1890 version)

namely “Pie Jesu” and ”In Paradisum” have additional “part of” relationships with other works

Soundtrack “CHAPTER IV PIE JESU (REST)” - MusicBrainz

and

I don’t understand what what first one is; the second is a soundtrack. It seems to me that the logical relational aspect of the MB “part of” relationship fails to capture some information - namely is there a true “parent” of the work. Clearly this would be a difficult question to resolve as a movement could be “part of” a major work and also of a revised version (although the Faure Requiem has not been entered so). While that would be legitimate, the others seem less so.
I found an older thread

which discusses this and the concensus seems to be that such links are not legitimate and should be removed. Is this still the current concensus? Or is there any actual policy? What, if anything, should be done in this case?

There is a new “included in” relationship that was actually meant for these kinds of works which are later included into works they aren’t really part of.

Ah, nice when a question has a single good and short answer. I made the edits:

To my surprise these were applied immediately rather then being queued for voting which was my intent. Not sure why. But in any case, please review and undo if this was wrong.
