I can't agree with you at all there: we're still at the point where the
computational costs of such attacks limit their real-world impact, which is
exactly when you want the *maximum* exposure to what they are and what the
risks are, so that people develop mitigations.

Keeping details secret tends to keep the attacks out of public view, which
might be a good trade-off in a situation where the attacks are immediately
practical and the need to deploy a fix is well understood. But we're in the
exact opposite situation.

Deploying segwit's 256-bit digests is a response that's already fully coded and
ready to deploy, with the one exception of a new address format. That address
format is being actively worked on, and could be deployed relatively quickly if
needed.
