Independent of the Pokepaste developer concerns, I don't see any reason why this feature needs to exist in the first place. I would disagree it makes pastes easier to understand; Smogon and Showdown convention for over a decade has been to look at stats by their relative investment, not their final value. Any other service using Showdown imports will be calculating stats based on EVs, IVs, Level, and Nature provided in the export, not looking at actual stats. So I'll reject it for those reasons, not Pokepaste developer concerns.
