We do not.  That is a patented technique, so we cannot even consider 
implementing it.

I believe you could if you implement it.

Detaching a curve usually means to split that curve into multiple curves, 
usually at some given point.  We do have routines for doing that (if not a 
succinct function, at least the building blocks).
