I don't think either of these addresses my use case, which is 
installing a port (or some ports) without a full checkout, but
having those few ports individually checked out into one directory.

In general that works quite well for me, it's only the above change
I now need in all my testing, and that change seems harmless to me.
Any objections?

I'll be happy to change the other similar cases as well.  Just not 
sure where this is now wrt. approval / rejection / don't care?
