Yeah, but is it really any worse than the situation now?  For some
MUAs (certainly the one I use) and for any determined spammer, forging
From: is no harder than forging Reply-To:

That's why Mailman originally tried to use the envelope sender for the
membership test, but that was doomed to failure for a number of
reasons.
