If I can't use "my" user(_at_)isp(_dot_)example (or similar vanity host
alias(_at_)user(_dot_)isp(_dot_)example constructs) whereever it pleases me
in a mail header, then it's not more good enough, and I'd
find a better ISP. The mail header is user territory. The
limit for this "hostage" issue is the MAIL FROM from my POV.
(And for the "errors-to" fraction that's already insane)
But that's only my personal view, ISPs are free to enforce
a more radical approach, Others might accept it and try to
work with Reply-To.
