Taproot, potential quantum bug, and general clarification
See Pieter's responses.
(1) seems ok
(2) Mark's concern is real, but worry about exposing the tweaked pubkey doesn't seem to be of a high concern to people supporting Taproot. In ref to Taproot exposing pubkey, &quot;numerous advantages (it's smaller, cheaper, and makes a number of more advanced protocols on top a lot easier).&quot;
&quot;TL;DR: public keys should be public.&quot;

What are the potential attacks against ECDSA that would be possible if we used raw public keys as addresses?
