Kelvin does still rely on each degree being 1% of the way between freezing and boiling so it kinda does rely on a variant reference point

The reference point is the triple point, and invariant.
Sure technically yes, but also celsius is now technically defined as just Kelvin plus 273.15. Degrees have technically been redefined as exactly 1.380649×10^−23 joules
Why is that only "technically yes"? It's precisely how the thermodynamic and empirical temperature scales are matched.
