If it didn't return a cursor, it would make sense to reconsider
calling it execute(). As it is now it returns the same that cursor
returns, it's pretty much just a contraption of a chain of methods,
hence the same name.

If you return just the fetchall list you lose access to results
metadata (description), nextset, and someone will come asking "can I
have executefetchone() please" the next minute :)

I'll play a bit more with it in the test suite (which is currently the
main body of code using psycopg3) and think about it.
