No, that would require massive performance testing of all alternatives.

The trouble with a bakeoff is that it's pretty darn hard to get people
to test in the first place, and then comes weighting the subjective and
hard performance numbers. If they're close in numbers, do you go with
the one which starts the least flamewars or what?

Could be. All was quiet for quite a while, but when RSDL showed up, it
aroused enough interest to show that scheduling woes is on folks radar.
