No, this is not true. DNS servers had for ages ability to forward
selected domains to specified list of addresses. All DNS caches have the
ability to do it for no reason.
Servers do not have automatic configuration of split DNS only, because
often do not have multiple connections. But I think VPNs could be also
used to interconnect networks and selected DNS forwarding might still be
benefical for it.
However, servers need a proper DNS service. Very often they depend on
DNSSEC for mail filtering. They should protect their precious caches
with signatures. DNSSEC disabled by default, even when upstream service
provides perfectly working DNS, is just failure on our side.
Especially on servers, when DNSSEC readines would be much more common
than on crappy cheap home routers.
Remote DNS does not have to be much slower. If you have dedicated
resolver on the same LAN as you, your own cache might not help you much.
Depends a lot on specific applications usage.

Servers don't need split DNS. Desktops do. Without a DNS cache, your DNS
will be slower. Without split DNS, your DNS may not work properly at all.
