Only if the people you reply to include the List-* headers. For example,
you didn't, so I can't use Reply-To-list for this reply (without
manually munging the headers of course). This forces me to use
Reply-To_All or to start cutting-and-pasting addesses. I guess that's
another reason it isn't so popular.

That surely is up to the receiver, not the sender. Furthermore, as it
will vary from list to list it seems impractical to have to set it
individually for each post if the MUA doesn't support it automatically
(Evolution doesn't).
