In their case, most likely yes. I honestly don't know and how don't know how many of their targets can be blanketed this way. The scenario I describe will not work for 8000 device types as you will end up with 8000 codegen libraries. Or that is, with my current implementation you will end up with that amount, as each target gets it's own little generator.
I recently swapped out a big chunk of my codegen code and let my code call the flutter cli, so then I generate a flutter project which in turn can generate a few clients (like web, desktop, android etc). I'm currently optimizing the way I keep state between generations: certain parts can/should be overwritten but other parts need to be kept in tact. Trickier than it sounds.
I highly recommend people to try building their own generators, scaffolding & tools. Very enriching!
