You can change the size of the tooltips, both new and legacy, by changing the overall user interface text size in the general options. Changes the text size and look of all text globally, of course, but not disastrously so. Still in caps, though. Also, fascinatingly, on the BlackBox Simulation's BN-2 Islander, the legacy version of the tooltips does show the variables settings when you hover over the switch or knob, so it is still possible, and therefore very easy for Asobo to turn this back on.
