Should be new artist created when using alias?

Earlier relevant discussion: When to use Aliases for artist name

So far, I’ve usually created a new artist if the alias was used to credit something, usually as writer or producer. However, apparently this is not the consensus view as you can see here: https://musicbrainz.org/edit/76527151

This seem to be overeager merging to me. Almost all of Tim Reaper’s production and writing credits are credited to “E. Alloh” or “Ed Alloh”. Right now, he only performs as “Tim Reaper”, so it’s still possible to just alias it, but shouldn’t we rather always create a new artist if they’ve been credited by their legal name?
