Having it on your PDC is just fine.  No reason for all DCs to do the work when one can and push the changes out.

btw - whAT OS

actually 'BEST Practice' is just the one server

disable on all others then play by zone

here is an older MS article mentioning that same point

and one of our older posts for Best Practices

Not all DNS servers are Scavenging servers, you can configure/promote DNS server to Scavenging servers, this can be PDC or any one DC with good health
