Is it possible to specify individual vertices to be unshared in this way? Selecting a point would create new points for all vertices at that point, rather than specific ones.

Please feel free to submit an RFE for it.

and define a point group prior to that

The group select button next to the group parameter should work too, but yes, it's not ideal. In tomorrow's build, Houdini 17.5.260 the Facet SOP selector should support points; it was a bug on my part that it didn't, since the selector should normally correspond with what the group supports. It's still not ideal, because of discoverability and Unique Points being off by default, as people have pointed out, but hopefully it helps.

You're most likely aware of this, reason for which I'm hopeful we're going to get an improved workflow.

Thank-you for the vote of confidence.

Not sure if I'm missing something, but doesn't this node operate on polys only?

The Unique Points option will work on primitives of any types. Also, Facet in 17.5 can accept a point group, in which case any points in the group with multiple vertices on them will be duplicated.

I'd vote for Point Split SOP

A Point Split SOP would be clearer than Facet, and it could replace Primitive Split and Vertex Split if it had an optional primitive or vertex attribute pattern to split by, (defaulting to splitting all points in the group, if the attribute pattern is not enabled).
