That's only a technical detail, tho: If we decide to preload seq.el it
should be easy to reverse the dependency (i.e. make cl-lib use seq.el
rather than the reverse).

I think I'm mildly favorable as well, but I'm not very interested in
putting the work needed for this to happen (IIRC there are some
technical issues to address before we can do that).

You can see my addition of pcase, lexical-binding, setf, cl-preloaded,
and cl-generic as a way to reduce this tension ;-)
