You could rescale it all to volumetric flow rate, then density doesn't affect it. Air density X volumetric flow rate = mass flow rate.
That being said, MAF isn't necessarily easier, yes in theory the math is more direct. MAF is susceptible as low engine speeds to reversion and skewed readings. Due diligence needs to be taken on MAF placement, and plumbing to ensure laminar flow. Quite a few GM ECU's use a blend of speed density and MAF until roughly 4000rpm (on LS truck engines) to where it switches entirely over to MAF. The reason It can do it here is that the intake pulsing has negligible effects on the reading at those volumetric flow rates.
TLDR; I would like to see this feature added, but it is not as easy as assumed.
Just my $0.02.
