No.  I tried to search for set functions like those, but somehow I
missed them 🤦

seq-set-equal-p would fit the bill but does not seem to be recursive.
For example:

  (seq-set-equal-p '(a b (c d)) '(a b (d c))) ⇒ nil

Nonetheless it is probably very useful in other contexts.  Same for cl
set functions.

Thanks,
Petteri
