This all feels a bit silly as I'm not terribly convinced time-between-texts conveys much about the process (THE BRAIN) generating said data points.

The flow chart for "Should I reply to this right now?" is pretty complicated; recovering that PGM is hard!

And as for signaling "busyness" -- that's better accomplished through delaying showing you "read" their messsage, no?

Is there a missing niche for a whatsapp wrapper that delays "read" confirmations by 3 minutes?
