I don't know what kind of functionality is usually switched on by the
zcml dev-mode. Are there any common examples?

Dev mode in Zope2 is turned on automatically if you run the process in
foreground mode and is very common to use. If any of the things
controlled by zcml dev mode affect performance or startup time in a
noticeable bad way, that would be worrying. If it's only additional
logging, development and debug helpers being switched on, that sounds
like the same type of functionality.

Not a bug. Just not a feature implemented yet ;)

I'd assume you'd need to add some logic into Five for this. Probably
register a different zcml handler for the directive as done for most
of the handlers.

I'd be +1 on this, if there's no performance or otherwise noticeable
drawback from it :)
