For some reason it did not get to the list, I have re-sent it.

Common sense says that there should be good compatiblity for many
years. But new "cool" trend is to break things, so I am not
sure. IIUC 'xnest' is incombatible with Wayland. 'xvfb' seem to
be derivative of 'xnest' so that potentially may be broken
(more precisely, if/when 'xnest' is broken IMO there is risk that
'xvfb' will be no longer updated and may bitrot).
One possible way to improve our graphics is to use Xt. Xt is basic
X11 toolkit (some other toolkits are built on top of Xt). But,
it is not clear how long Xt will be maintained. Note: I do not
think there is worry in the next few years. However, we are
using code that is 30 years old and preferably improved code
should live longer.
