This is a thing of the past (partially). All hours count towards the ATPL which are required to be flown with two pilots, either because of the manufacturer (part 25). Or because of the autority, which in case of EASA does not permit single-pilot commercial operation of multi-turbine aircraft (with some exceptions). So flying an Eclipse or a Metroliner under an AOC will also count towards unfreezing your ATPL.
And that 20t (or any other arbitrary company limit) limit still applies with some carriers. But right now, most are happy enough if you have flown anything heavier than a parasail long enough to get your license signed.
