Is that really the only problem?

I thought the main problem was that GNU ELPA's seq.el can't use
cl-defgeneric since GNU-ELPA's cl-generic can only dispatch on
EIEIO types.

As for preventing byte-compilation, yes indeed you can and I've done
that a few times recently.  See for example dts--using-macro in the
dts-mode package (in GNU ELPA).
See also TeX--if-macro-fboundp in auctex's tex.el.
