Not so fast! For many of the OEIS users, the suggestion that a sequence
satisfies, say, a lgdegf recurrence is not a moment of enlightenment.
As with this case, many, perhaps most users have to spend several hours
trying to figure out what this means. This is fine if there is some
reasonable chance of an actual fit; but it seems to me that at least
those tests done by Superseeker that wind up doing a polynomial fit to
data should be so constrained.

Well, if one has enough terms, than that is certainly something
one can do oneself. Just feed it N-1 terms and check
its prediction against the N-th yourself. But since the gfun section is
only one of many things that Superseeker tries, I don't want to
incorporate your suggestion into the program as a whole.
