Is there any value to this? Apparently it used to work just because that 
command never did anything (rather than return an error). Why not just 
reinstate that behavior instead?

There's doesn't seem to be any reason to implement the single-register 
case unless there is some legacy use of it. There's a good reason gdb 
tends to use the "register block" thing, and it tends to be easier to 
implement too (no crazy case statements etc).
