I have a number of (former) customers using it as primary storage. You 
set up mirrored metadata, mirrored data, and you get a nice HA-like 
system (they have some issues with HA daemons, but I understand this is 
being worked on and will be delivered soon).

It is IMO excellent for this.  Back it with zfs on the units, distribute 
your metadata and mirror it.

Can be done, but I know very few people using it (again some former 
prospective customers).  CephFS is somewhat behind for this use case, 
though it should be reasonably stable/performant.
