I've seen both kinds. GF projects where the senior devs feel that they have to get something right from the beginning, spending a year just on that piece (a set of widgets, a data ingestion framework, a state machine that covers the entire underlying algorithm). And other GF projects which have frequent updates and are open to development with very few speed bumps.

Of course you can call out the former examples as incompetent or hubris, and they will probably occur less and less, but nevertheless they exist.
