As I've said elsewhere, not sure trying to do a mass conversion of this
is a good idea. People may not be used to the interface, but it is
consistent and has its use. The recent flurry of conversions show that
those also risk introducing new bugs in code that is currently tested
and correct.
By giving the script kiddies another toy like this, the influx of broken
patches is just bound to increase.
Would also be good to CC the PM maintainer on this issue.
