 Well, that's how BOSCH has done it since umm .. forever ..

 There are *compensations* to MAF/rpm to make the pulse width up, but the
 basis for fuel injection time is MAF signal ...

 Also, things like delta MAF are used to signal acceleration and also
 throttle position, etc etc etc ...

 No, not unless the # of BLM cells (or adaptive locations) is equal to the 
 number of possible fuel map cells under those conditions .. so that EVERY
 point in the fuel map is compensated .. to it's needed adjustment
