Thank you!

But... could you perhaps also add C-s C-u C-y, as I suggested?  If not, 
why not?  The prefix argument is currently ignored by C-y.

I believe accessing the new feature with both C-s C-u C-y and C-s C-u M-y 
is useful: C-s C-u C-y is useful to immediately enter an interactive 
selection (it's convenient because it only uses the control modifier), and 
C-s C-y M-y ... C-u M-y is useful to enter an interactive selection while 
using the non-interactive selection.
