and probably the change will not be hard for them to support, but I'd like
you to remember that the tool users will need to update them for the change.

The situation where we need to update the tools for new kernels is usual, but
there are not many cases that they cannot even start session, and this change
will cause it.  Personally I wonder the change is worth forcing users to update
