What SSS does is indicate a players potential dps and whether that potential is at the required standard to take on the content.
for this task SSS is a great tool. and making it a requirement would then block people that don't have that potential from joining party finder groups.
The amazing thing with this is how no one even bats an eyelid and it's apparently o perfectly acceptable for players to be that lazy. especially if that laziness is your reason to not add a check feature to pf groups.
