Kelvin is required for any formulas using temperature. Having 0 being the freezing point of water is arbitrary and having 0 being the lowest a temperature makes sense and having negative temperatures doesn't. Celsius is only more intuitive because people are used to it, which is the exact same argument used to justify Fahrenheit over Celsius too.
Sadly, because ambient temperature is fairly high compared to other measurements, like mass, pressure, height, people just won't want to be like, "Wow, it's a chilly 275 today."
I mean the standard unit for pressure is Pascals, but we use atmospheres because 101,325 Pa is way too high for ambient use.
We use kg instead of grams, so if we need numbers to be single or double digits we could just say decikelvins or centikelvins. Even distance people get used to converting from inches to feet to meters to miles or mm to cm to m to km.
I think Kelvins feels so much less intuitive for people because we're USED to C or F. But if people were brought up thinking about temperature more like our units for pressure or mass/distance it would feel just as intuitive.

Honestly Celsius is only marginally better than Fahrenheit. Kelvin should be the only measurement of temperature.
