Right, I would agree.
SooperLooper works well on its own for interactive use, with e.g. a
guitar and MIDI foot pedal. When I'm trying to play along to a song
driven by ChucK, the whole setup becomes a royal mess, MIDI/OSC sync,
mixing audio streams via jack, etc. etc.
The interface I'm looking for is an API within ChucK with just those
four methods, record/overdub/undo/redo. That way I can just use
ChucK's internal timing, run the looper programatically, and keep all
the audio within ChucK.

So I've heard. ;)
Thanks, I will peruse those examples again.

Hmm, yes, those would be the devil(s) in the details.
