Both appear useful to me.
May be unified by a keyword "rec" for linear recurrence with
constant coefficients (?).

But who will add the keywords to the very many seqs where they apply?

Uhm, I vote against conj-* keywords.  A comment will do.
Note that short sequences allow for a lot of conjectures
that vaporize with the next one or two terms.
