XP is a good baseline for comparison: it is the starting point of this lineage of Windows being what everyone had. 2000 was uncommon on the desktop for home or small/medium business use, NT even more so, those environments being sold 95/98 (and earlier 3.x) instead.
It is getting worse, and some of it is back-ported to Win10, so it isn't as simple as comparing Win11 now to Win10 now to note the differences.
Comparing from either base point in time is valid. There are probably win10/win11 comparisons out there if searched for (if not, maybe someone reading this wants to write one and get the attention from publishing it :) )
