Do Snorlax still hatch?

Highly unlikely. You can get a Munchlax from 7km eggs, and that's the baby form of Snorlax - so far when they've added Babies to the Eggs, they took out the evolved forms.

On the bright side, Munchlax has a 25 Candy/10,000 Stardust cost to unlock the 2nd Charge Move instead of the 75 Candy/75,000 Stardust cost. And now with Outrage as a potential Charge Move, it's a viable attacker in some situations.

No, but you can hatch Munchlax from 7km eggs and evolve to Snorlax

I hatched my last Snorlax from a 10 km on 4th December 2018. Thought they were still hatchable but not listed anymore on any sites egg list so was probably taken out at the same time Munchlax was brought into the 7km egg pool.
