I think the real reason is that Standard is very outdated by now and offers no handling for worlds with only baked lights.
In that sense Rero Standard will be an improvement already, but Filamented would be even better. It's an improved PBR shader based on Google's filament work.
Lack of light probes and reflection probes is the world author's fault, but in every other way it's pretty clear Standard was made nearly a decade ago. We've come a long way since then.
