Of course you are correct, but I am not talking about that. His line is:

server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbindd, 
ntp_signd, kcc, dnsupdate

What I am proposing is:

server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbindd, 
ntp_signd, kcc, dnsupdate, -WINBIND (upper case for emphasis only)

I was proposing the same line he already has but with the ADDITION of 
explicitly disabling the internal service instead of doing it implicitly. 
 I know that winbindd is the new default but what if the internal service 
is NOT being correctly disabled and it conflicts with winbindd? Are you 
certain the eventual bug is not here?
