First three letters are NTP and at the moment, Samba only supports the
use of ntp, whilst other time servers may claim to work with a Samba
DC, they are not supported.

please don't confuse ntp as protocol and ntpd as implementation
"Samba only supports the use of ntp" is nonsense

what pieces of the protocol does samba need so that as example
http://www.openntpd.org/ is not a drop-in replacement?

But according to following command output chrony on my samba dc
already serves the windows clients:
alexei at ubuntu-dc:~$ sudo chronyc clients
Hostname                      NTP   Drop Int IntL Last     Cmd   Drop Int  Last
