Actually, I have no problem with that one. Clearly, there's been
problems with WP installs being able to send emails in the past
because of the various from headers and such, making them easily
configurable (either via the admin menus or via filters and plugins)
is a good idea. It has been demonstrated that no one setting works for
everybody, so an option is more or less a requirement at this point.

I'm not quite understanding why any plugin can't hook in the same way
Akismet does and do more or less the same thing. If some setting is
not set, plugin hooks and displays a "hey, notice me!" thing.

I don't quite follow what you mean by "workflows", as such. I'm
opposed to adding a new table specifically for them without some kind
of better explanation as to what you're talking about. Let's try a
question and answer format:
1. What is a workflow?
2. How does it work?
3. What does a row in this table represent?
4. What can a workflow do that you cannot do already with existing
5. How could the core benefit from workflows (leaving out what plugins
can do entirely)?
Generally speaking, I've noticed "generalized" type of things tend to
make it into core when they can specifically improve the core itself,
and then they become available for plugins. Very rarely do you see
things get in so that plugins can use them. Example: SimplePie
recently replaced MagpieRSS in the core. Why? Because the new
dashboard makes a lot more extensive use of feeds, and Magpie didn't
cut the mustard anymore. This despite that fact that many people have
been wanting SimplePie in for a couple years now, so that they would
have a decent RSS parser in there to use.
