Most X implementations do support SMARTREFRESH like capabilities.
MIT only says you can't depend on it being there if you want your
product to be completely transportable to all other servers.

However if your applications depend on COLOR or other capabilities
of X11 that are not universally available on all machines (another one
is speed) then you have the same problem.

SMARTREFRESH is a very nice feature and applications may depend on it.
All they need to do is say so in the sales literature so that the
customer makes sure their Xterminals/workstations have the required
set of features to support that application.
