For my amd64, rpi2, and powerpc (non-64) activities I can do such things rather 
than answer prompts individually --and have sometimes.

But for my libc++/xtoolchain based powerpc64 environment I've got a couple of 
things it lists for delete-old that I do not want deleted because I've got 
special things in place. If the check-old list is fairly short I answer 
delete-old individually. If the check-old list is really long I delete all and 
run a script that puts back my couple of oddities (which happen to be symbolic 
links).

Thus I tend to expect and use the individual delete-old prompts at least for 
one of my contexts.

I do have a tendency to work similarly across contexts even when local 
optimizations could be made. So I tend to treat amd64, armv6, powerpc similar 
to powerpc64 for check-old/delete-old use. [Another example: I'm unlikely to 
use ports-mgmt/synth on amd64 because I can not use it on armv6, powerpc, or 
powerpc64.]

And that explains why I noticed the issue even though I currently do not have 
access to the powerpc64 or powerpc machines.
