Is it ever possible to have a discussion with you without feeling
castigated for my views and opinions?  You asked for opinions, so
please accept them benevolently, even if you don't like them.

My vote is for the default that keeps the buffers.  I see nothing
wrong with having a lot of buffers in an Emacs session.  Personally, I
regularly walk through all my buffers and kill those I no longer need,
because I use desktop.el to restore my sessions, which would otherwise
grow indefinitely.  It's no big deal.  It is much less of a big deal
if sessions are not restored.

I don't see why that would be true.  Please elaborate.

You asked for an opinion, that's mine.  IME, good engineering
anticipates such requests before they are voiced.  If you can only
resolve a controversy applying your personal preferences, it's a clear
sign that someone, somewhere will be unhappy about it.
