In my configurations, desktop.el upholds that promise.

If you are unhappy even with the additional hook proposal (you didn't
say), then I guess we have nothing more to discuss here that could be
useful.

Once again, when I restore my sessions, I see a flurry of messages
that inform me of what's going on.  And my sessions are very large, so
they take a relatively long time to restore.

There's nothing wrong with desktop.el per se, not in the common use
cases.

"Few" as in "none".

Again, this part of the discussion is not useful.  If an additional
hook could fulfill your needs, please feel free to install such a
change, and let's move on to more important stuff.
