Can the principles of enterprise architecture be inherited from a Saas solution?

I agree. The vendors sure do try very hard.

At that level, I don't consider it to be Enterprise Architecture. Though, it is helpful to understand the details at lower levels, to consider how this might impact upon your upstream solution.
