I use obscure parts. For example, just this month I've used a part that the manufacturer doesn't admit exists on their website, and a part where the manufacturer doesn't even have a website, and neither is anything widely used. But there's always a small community of people who use the part, and we cling to each other and compare notes vigorously.
That’s only the case if you use the small (tiny!) subset of parts that everyone uses.
If instead of using some nice and common stm32FXX MCU, you need to work with some obscure Renesas or Fujitsu for example, prepare for a world of pain.
The good thing with web stuff is that you can swap frameworks until one does what you want nicely, and leave it at that. You can’t really change the IC in your board just because the I2C module is doing something weird.
