Why do some HAL functions in the KSDK use the BME but others don't?

I'm writing some time-critical code, but using the KSDK HAL and DRV as a guide.


Wherever possible I'm using the same macros provided by the HAL, most of which seem to use the BME, but here are some cases (like enabling a shifter status interrupt in the FlexIO), where a manual read-modify-write is used so I'm a bit confused  why the BME has not been used.

Can anyone shed any light on where it can and can't be used?
