So is there a bug in process-adaptive-read-buffering, or not?

When does it do that?

IIRC, that's what it is doing already -- timers are reset by
start-process and on write, and the process is ignored in adaptive
read buffering after it has been deactivated.

Have you observed such effects?

I'm probably overlooking something obvious...
