	And if it makes their life easier, then I approve.
	1) something visibly changed, that
	2) affects the default system shell and therefore a _lot_ of

	3) without warning or documentation (e.g. a single line entry in
		src/UPDATING), and figuring out what happened is, in your
		words "really hard to discover" for the casual user.
