But, what if some vendors have already implemented some on-premise
features using the Nova extension mechanism, to achieve strategy of
product differentiation themselves based on OpenStack? IMHO, the
DefCore has already give some advise about what's OpenStack(you must
pass through a lot of predefined tests). If vendors can not provide
extra features by themselvs(which is backwards compatible), they will
lose a little competitiveness on their product.
I'm not very sure whether or not my understanding is right, but I
really concern about the what's the right direction for the vendors or
