While such drivers will generally get evaluated too late to be of much use during animations, it can still be useful to allow using drivers to control a whole bunch of NLA strip properties (i.e. syncing NLA strip timings via a single property/control). Keyframe insertion however is still not allowed on these properties (and an error message will now be displayed when trying to do so, instead of silently failing), as it is useless.
