Well, the Pico has bags of Flash, so we're nowhere near having any problems with that. On the original board it's getting more tight, but I have spent a lot of time recently trying to lower the Flash usage - to the point where I even have a tool that scans over the code finding sequences of assembly instructions that are repeated and which could be merged into a single function!
Generally a lot of the tweaks and fixes don't use a lot of memory though, it's just when there's completely new functionality.
It is getting extremely tight on boards with 128kB like the Olimexino, and I do often end up cutting features out for that when I don't think they'll be used.
