Yes - its by saying.. but its possible.
and its not so hard to run test l3+ with test on 24-48h with chosen XMR coin be paid.
Difference very small. So You with l3+ can work and mine XMR (NOT DIRECTLY) but no matter how - if its still profitable and can do it - you can.

Scrypt not scrypt - asic or not.. Possible  YES! and almost price go like with GPU directly.

Everything is possible
