So we can apply diff + patch -p0 directly on the features XMLs. The problem with this is that if the user then does: features:chooseurl foosnarf 2.5 and foosnarf also uses an older version, they still get the older version. This requires the user to to patch a BUNCH of features.xml files. I'd definitely prefer something that would allow overriding of information in the system directory (or pulled in), not require changes to stuff in the system directory.
