bug#37976: 27.0.50; Dependency reversal of seq-subseq and cl-subseq causes regression when using seq from ELPA

This new cl-subseq only exists in Emacs's `master`, right?
So they're running Emacs `master`.

Why would they use "seq-subseq from MELPA" when they have the latest
seq.el built into their Emacs `master`?

Could we have some more data, such as which package (name and version)
pulls which version of `seq` (and how does it say "from MELPA")?
