It gives a disproportionate meaning to 0 without real physical consideration, eg:
- 0.1⁰C ± 0.1 (wow 100% relative error) - 273.25K ± 0.1 (meh 0.04% relative error)
Beside that if there are uncertainties involved, one should do proper propagation of uncertainty anyways. [1]

What would make a difference is to change to https://en.wikipedia.org/wiki/Thermodynamic_beta
(Essentially the same difference as miles per gallons vs litres per 100 km.)
