When Apple announced the 2021 Studio Display 27" & 2021 Mac Studio they neglected to include the replacement of the 2020 iMac 27". That iMac is now 34 months old.
Apple & many others said that you are better off with a separate 27" display + Mac Studio/mini as the monitor wouldn't be "wasted" if you upgrade.
Now there are users out there that replace every refresh but there are others who'd only replace way longer than that like say after the final macOS Security Update was released. This typically occurs nearly 10 years after that Mac was 1st shipped.
After a decade that display would be half the display resolution, half nits of brightness and color space of currently sold displays. Not to mention wear and tear would reduce the published nits.
Example:
2012 iMac 27" has a 2.5K resolution display at 300 nits of brightness with a non-P3 color space. The 2021 Studio Display has a 5K resolution at 600 nits of brightness with a P3 color space. If the 2012 "display" was separate from the "Mac" would you still continue using it for another decade?
It would be showing its age by now after an average daily use of ~8hrs/day for ~3,650 days.
Physically speaking back then miniDisplay port was used 10 years ago and was replaced shortly after by USB-C ports that is being used today. Will USB-C form factor be used by 2033 or 2043?
Yes, we can use dongles but the point is it is that old. Maybe after a decade's use an upgrade is in order? It would be like using VGA or DVI in 2023.
