if by "how hard it is to implement a solution" you include the effort required
to identify and upgrade all existing software that depends on existing
behavior, and if you also consider the additional effort required to implement
and deploy any future software that needs long-lived sessions, I might agree
with you.  

but we must not fall into the trap of saying "here, I rewrote the kernel code
to do this, and it was easy, threfore the solution is easy to implement".
