It's completely up to you really.

Note that Dom0 in a typical setup also runs several services for all
VMs, so in order to not bog it down too much it might be a good idea to
not run any user workload inside it.

Also from a security point of view, it is probably good idea to not
expose unnecessary service on Dom0.

All in all, personally I won't run any  public facing service in Dom0.
