IMHO, this should work. Maybe issue E_STRICT, but even then I'd think
it's not really necessary, I can't see any purpose E_STRICT serves in
this case - since $this is not used, no potential bug is averted, as the
code works exactly as it was supposed to be working.
Such code will break, not in the first place but later on!
You propose that every instance method not using the variable $this
internally will be magically a static method and can never ever be
changed to use $this without an bc break.
