If you're asking me, I would say that's OK.

1. The keyword domain expands very slowly, if at all. CVS was around for
a long time with a stable list of them.

2. There aren't that many attributes that make sense to use in this way.
It's very hard to imagine the hot new keyword of 2009.

3. Upgrading the client isn't difficult.

Please bear in mind that the whole property-setting feature is pretty hard
to grasp. Lack of validated input only makes it harder to get right.
