But I'm planing to merge this only after seeing the main drivers/i2c accepting the new terminology. So we don't have a risk of that getting push back and new names there and we having to rename it once again.

I believe although not necessarily/directly i2c, I believe they are related and could benefit from the massive single shot renable. or do you have any better split to suggest here?
