Yes, I've done something along those lines (and also required the very
small subr-x).  AUCTeX is traditionally very conservative with
dependencies but we should not limit ourselves by not using basic emacs
functions in the common libs like cl-lib, seq, or subr-x.

I'm closing this report.  Thanks for the explanations, Stefan & Eli.
