Im sorry Michael, but i dont see your point: do you mean the fact to call
nreverse twice?
nreverse is in fact very efficient;
and last already use nthcdr in its implementation.

Please elaborate more.

As i mentioned, they are not exactly the same function as seq-take.

Why i need to pollute my global space with all seq.el just to use this
fundamental operation on a list?

I we want this in the core, we may also consider to implement such
functionality in
src/fns.c
