Sorry, I don't understand what's under this link and how some Github
repo pull helps in this discussion. I don't see there any text, which
could help.

I also do not understand why this pull proves that you can change
existing mediatek compatibles (we talk also about ARM, which is shipped
to million of devices) to ralink without breaking the ABI.

I do not see how choosing one variant for compatibles having two
variants of prefixes, complicates things. Following this argument
choosing "ralink" also complicates!
