We could also say that if protocol part (https://) is missing, it's implied automatically. So just:

bitcoin:1abc........?r=bob.com/r/aZgR

I think that's about as small as possible without re-using the pubkey as a token in the url.

BTW, on the "make qrcodes more scannable" front -- is it too late to change BIP 72 so the new param is just "r" instead of "request"? Every byte helps when it comes to qrcodes ...

Not too late, assuming there are no objections. Smaller QR codes is a very good reason to change it.
