The intro para seems odd in that it starts talking about adding features,
then it immediately says it is going to discuss how to remove a feature.

Regarding "when to unprefix", I'm not sure the CSS WG has recommended
removal of prefixes upon entrance of CR. It has recommended the
implementation of the unprefixed flavor (of CSS syntactic features), but it
has not gone any further than saying "ideally, when you implement the
unprefixed version [should you drop the prefixed version]".

Also, it is worth noting that these CSS WG recommendations have not
necessarily been accepted, applied to, or promulgated by other W3C WGs.
