Dropping support for such newer Intel Mac's would not make any sense in my opinion. There will be lot's of Intel MAC's in circulation for some years. Apple generally gives good OS support for MAC, so an Intel MAC from 2020 isn't going to be abandoned by Apple sometime soon. Hence leaving so many people out of their ecosystem by supporting only M1 series and beyond would be foolish.
Having said all this, the official word can only be given by Adobe and there are not many active employees on this forum. You could try asking Adobe support or send a tweet tagging @Adobecare
