Thanks for the status report; it sounds like a lot has to be done.

I, too, remember that Dave was discussing these issues, so I'll leave
it to him to comment on this.

Yes, agreed.

Please do add these two environments.

Hmm... not sure how is this relevant to the issue.  Are you saying
that Emacs beeps in some modes, but not in others?
