See plenty on older bikes normally, my last frames have been 07-09. For me the reasons that things go "Out of date" are things like head tube sizes (left 1 1/8" behind), lack of chain guide mounting, rear bolts etc. things change rather than go out of date, if you can still get spares for your frame and it still works for you then carry on.
Can't see it on the map.. where is it? 😉
Lack of disc mounts (and not that interested in the faff of adapters) was the reason to move a frame on for me. Still have the bike, just in another role.
Old bikes don't fade away, they become Retrobikes! 😀
My newest (as in most recently purchased) bike is my oldest. '03 I think, could be older.
Dandyhorse?
Technology goes forward. The bikes of 5 years ago aren't visually much different to now and people seem to think that because suspension design hasn't changed, bikes haven't changed overall. But geometry has changed significantly, and the advance of the "do everything" bike is phenomenal.
5 years ago my bike had none of these things:
Dropper seatpost
10 speed Shadow+
Useable 1x / narrow-wide front ring
Aggressive geometry
Tubeless
Wide bars
*
Compared to my current bike, it was rattly, weighed several kilos more and was less capable both going up and down.
Was it less fun? No, probably not.
YMMV
*I purposefully didn't mention wheel size.

Pish - my [s]Dandyhorse[/s]Maverick ML8 is well old - and had loads of mod cons back in 2005:
rapid rise mech; dropper post; fab geometry; tubless; wide bars etc
- it will always be the "best bike in the world" [/maverick owner off]
Granted it did supersede the 3 mavs I owned before - they were also the "best bike I've ever owned" too 🙄 🙂
My pub/station bike is a '39 Triumph. It gets me to the pub/station. Pre pneumatic tyres old I'd classify as " too old"
