Re: [gentoo-dev] Dependencies default to accept any slot value acceptable (:*), can we default to :0 instead?

I think we're better off with defaulting to slot 0 rather than
erroring/warning if no slot is specified.  Otherwise we're basically
going to have to modify every ebuild in the tree to add the :0 (unless
there is no warning when only slot 0 exists, but then another slot
could be added at any time and what is the behavior then?).

Or we could do both - we could define EAPI 6 as having :0 be the
default slot behavior, and we could have repoman offer soft warnings
on earlier EAPIs if there is no explicit slot.

(I'd even suggest making the default :0= except that there is no way
to override that as we defined not depending on a subslot as the
absence of any operator and not a different operator that is simply
defaulted.)
