Mostly. I2C/I2S not as standard (although available for expansion modules). ETH, IR, PWM, Temperature, Touch, DAC, all no.

All the rest, yes to a greater or lesser extent.

People may be reluctant to share as the dumps may contain personally identifiable information (not just VINs, but also things like latitude and longitude coordinates of charging, parking, etc).

Having problems understanding you here. When you say ODBeleven do you mean OBDII (OBD 2)? We don’t have any specific glossary of terms for these, but there are plenty on the Internet. The wikipedia article on OBD-II PIDs and accessing it CAN is a good starting point.

https://en.wikipedia.org/wiki/OBD-II_PIDs

If you are looking at vehicle support, the article on that developer page is the best starting point we have:
