Majority of user are not using it, it's wasting time and resources, 
faster boot time.

When I turn things  "off" or disable them programs should not be wasting

to be running an constantly listening or checking and wondering if they 
are gonna receive "instruction" to process and further instruct
a program that I have already disabled.

Unless you force them to use
IPv6 and give them IPv6 compatable hardware they won't switch.
