My 8 year old MacBook updated first time.

Previous generation machines up to around 2013 (approx.) can run Big sur. That I would class as forward compatible. Older machines (pre 2013) cannot, for example my 2011 MBP is limited to High Sierra.
Not strictly true. My late-2008 MBP (upgraded to 8Gb RAM) happily runs Catalina. Just use dosdude1's patched OS. He hasn’t ported Big Sur yet but given its problems I’m not surprised!
