The evolution of KW

[MidTowner]

I know the university tries to foster a startup ecosystem in the entire region and overall they don't much care if they are in R&T park, Northfield, Innnovation District  or Cambridge.

And nor should they. As you say, companies need very different types of facilities and locations depending on their stage of growth. If the desire is for start-ups to scale, they need to be able to move to bigger facilities (which doesn't necessarily mean outside of the centre, but often does) and still feel like they'll receive contact and support.
