What about for a scope that slews to different parts of the sky?  Does an
athermal OTA typically suffer from 'slew-induced focus shift?'  Does an
athermal OTA that is immune to 'slew-induced focus shift' cost too much, or
end up being too difficult to fabricate?

Don't know - have no experience to answer these questions.  It's always a
tradeoff between making the scope more robust before operation or spend
time working the problems as you use the scope.
