I expect that intel Macs don't have much steam left in terms of macOS upgrades. The first x86 Macs shipped in 2006 and Apple dropped PowerPC support with 10.6 Snow Leopard in 2009.
I assume anyone who bought a Power Mac G5 in 2006 knew what they were getting into.
If anything, I would rather them stop doing stuff like replacing a rather idiosyncratic but well-understood System Preferences panel with a half baked replacement that goes against half the Mac HIG.
If dropping support for Intel Macs meant huge performance wins for ARM Macs, or freed up the team to work on huge OS improvement I could understand it, but neither of those things seems to be true.

Not quite 100% on topic but useful for those with unsupported hardware.
Sure, take the upgrade if you can though.
