cpu have become hacks in silicon - adding removing altering features, 
claiming and revoking compatibility: and you/we may see this effecting 
base cpu without warning

HOWEVER that the example you cited is for existing CPU it works for so 
answer there is: leave it alone it works for those (or most of) :)  it 
the CPU that aren't those which may be a problem.

it's safe to say avoid dependance without specific need and check 
otherwise - and defer to user to set it.  i always have to select 
options anyhow since the span of features wished to support is is custom 
to release, and releases today are typically "one off", once off the 
shelf it is hardly supported further.

have a good summer, thanks
