The two floors above ground level had their windows (all save one) installed by Saturday morning. Huge panels of glass - very nice. Additionally, the park looking upper penultimate window bank is complete.
As someone who lives at Northpoint and overlooks the park and T|20, I would not have a problem with greater height but beyond funding I'd question what would compel developers to "push" Northpoint in that direction. Labs don't require that height, whether that many "affluent" or "spendy" folks who might live in Northpoint would choose to live there over nearby zones with more established retail and eats, and whether the infrastructure (a small web of planned roadways among the yet unplanned dust bin between T|20 and 22 Water) would support something large are points on a very inexhaustive list.
And then there's capacity: Northpoint went from severely undercapacity to a lot closer to neutrally constrained: the hot dog building finally looking like something from the current century (glass!), 22 Water, T|20, and Phase III of Avalon kinda/kinda not planned ... And several condos in Northpt that haven't sold because they're 1bd/1ba for $700k+. But then we'll get a new Lechmere so there's that...
