If you've got a Git repo you're happy with, I recommend converting it
with hg-git. Putting CVS in the subject line is misleading at that point
though.

This pretty much says it all. I've never even heard of that extension,
so I can't say I'd recommend it. While the fastimport scheme is
advertised as being agnostic.. it's really pretty Git-centric in its
design and data choices and thus we've never been very interested in it.
