Interesting. It's not really the case here, but I imagine how it is

That's an option, but I wonder if we could do without it:

One way to avoid that, is to generate project names on the fly, in a 
uniquify fashion. If base directory names are unique, use those. 
Otherwise, prepend their parent names, and so on.

And we won't need a separate command. The exact strategy could be a user 
option, though.
