Very clever, a modification of the autobaudrate function that used to be
popular. I suppose you'd be limited to fairly low bit rates (relative to
clock speed) to get some resolution on the capture. In some apps (distributed
polled sensors perhaps) it could work well (retry in case the slave gets
the baud rate measurement wrong due to noise).

Have you actually tried this?

Best regards,
