Default keyframe interpolation

I was watching a YouTube video of CoSA After Effects 1.1, and noticed this long-forgotten gem in the prefs:

...which reminded me of a feature request I made ages ago (but has long disappeared in the transition to this new-ish discussion forum), and that is to be able to set the default keyframe interpolation mode. I often have to tediously go through many keyframes, setting them to ‘easy ease’ (F9). I know that it’s possible to set the spatial interpolation mode to linear (or not) in the prefs, but it’d be nice to bring back the long-lost option to set the default temporal interpolation, don’t you think?
