Hmm, maybe that method is SPI in that context (it maybe appears to be that way in the docs), but it also looks like it may have been around since around 2007 in quartzcore, from some googling. As always, try to test.
If anyone has 10.7 and can give the plugin a spin it would be nice if you can report back to list.
