I don't concretely know, as I have not used them myself.  But I suppose
that the seq- functions do the same jobs as the cl- sequence functions.

It is ok for a decision like this, about which of two alternative
solutions is better, to be somewhat subjective.  But it is clearly
somewhat objective too/

The concept of "overreach" is not applicable to a technical decision
like this.  This isn't about respecting or not respecting anyone's
personal rights.

Surely we should not accept a moral principle that Emacs should
contain all the alternative solutions that are at least halfway
acceptable.  We must be able to limit what we include.

That is true.  This would affect the CL sequence functions, of which
it seems many or all are defined in cl-seq.el.

The overall issue concerns the CL functions in general, because of the
way they tend to be alternate versions of important facilities defined
by Emacs Lisp.  Having those sets of alternatives is a kind of bloat.
