They're also literally just not pushing code to AOSP anymore. QPR1 still isn't available. It probably will be, eventually, but this year it's two months late, next year it's six months late, then nine months, then "eventually" and then finally only to OEMs.
I don't think Google looks at any of these forks as threats; they just don't care.
