people don't necessarily buy stuff that's not ungradeable.  They buy 
stuff which has a support lifetime of finite duration.

Manufacturers have no incentive to continue to produce software updates 
for equipment which they stopped selling N years ago, yet the production 
lifetime of the product may well exceed the manufacturer's sales cycle 
for the device.  There aren't credible reasons to think that the problem 
of equipment obsolescence is something that can be fixed by the IETF.

This shouldn't stop the IETF from formally deprecating standards which 
are known to be dysfunctional.
