Both the new and the old kernels do remain bootable.

Boot the new kernel, install the new tools, and you're done.
Or, installing the new tools then booting the new kernel would
also work fine.

I can't see any way you could possibly end up with an unmanageable
machine because of this change.  [ no, thats not a dare ;) ]

Iff you have mismatched kernels and tools, you would be unable to do
things like view/change EAs or ACLs, or restore dumps which have EAs
(because xfsrestore uses new/old syscalls, depending on its version).
There are no on-disk (fs) or on-tape (dump) format changes here, so
as long as you align your versions, everything should be fine.  And
if you don't, the consequences wouldn't be catastrophic.
