Is it possible to, without any extra knowledge, send a transaction back to whoever sent you monero?

In say, bitcoin, I know the address of whoever sent me btc, so I can send something back to them without them providing us their address "explicitly". Can something similar be done in the monero protocol?

Looks very interesting.

Blockchain bloat indeed is an issue here...

"bloat" would be an exaggeration. if you take 1 in / 2 out transactions as representative, it's a ~2% increase in transaction size (presuming knaccc's numbers apply to the presently used Bulletproofs+ transaction format).

If it's really only a 2% increase it seems worth it imo...
