Yes, you are right. The master does not show this one. But as far as I 
understand to this problem is not in the virtual hotplug, but in the 
PINs of the card creating the virtual slots, isn't it?

It was internal/offline discussion, mostly theoretical (based on the 
mails, comments and issues), because I don't have any cards exposing 
more PINs in this way and that would make a difference of the both 
libraries to test.

 From the discussion, what we would like to avoid is to have two 
(basically same) libraries in the OS for several reasons (p11-kit, ...). 
The inception to make the other symlink came in the mailing list more 
than two years ago [1] without any follow up. The pursuing the solution 
without virtual slots (single PIN) sounds reasonable for most of the 
cards. But still I might miss some part of the current behavior so 
correct me if I am wrong.
