	Thankfully vendors are perfect :-)

	I understand your problem, but then what is the acceptable time period,
hardware life cycle of 7 years sound good enough?  Could you say by 2024 all new
releases could be compliant with a new operational practice?

	I've been actively watching the leaks for nearly a decade now, another 7
years would be quite sad, but at least better than never.  I'd rather try something
because repeating our mistakes for the next decade is unpalatable to me.
