No, they are not enforced. 16/32 are official supported number of nodes. 
Basically, this is number what was tested and known to work reliably. 
This doesn't mean corosync doesn't work with bigger number of nodes. 
Eventho I'm quite surprised that 64 nodes really works.

Variables you can try tweak.
- Definitively start with increase totem.config (default 1000, you can 
try 10000)
- If it doesn't help, try increase totem.join (default is 50, 1000 may 
work) and consider increase totem.send_join (default is 0, 100 may be 
good idea).
- As a last variable, increase of totem.merge (default is 200, 2000 may 
do the job).

And definitively let us know about results. It's quite hard to test such 
a big amount of nodes so some of the variable may be sub-optimal. When 
we know which of variables are victims, we can change their defaults.
