It's only a problem when the MAF is too small for the given airflow and the signal starts to max out. The MAF wouldn't be able to read higher anyway, even if it was frequency based. I'm not convinced it's really better regardless, BMW could easily use that system if they wanted to, but they've continued with a 5v signal instead. The resolution of the signal has more to do with the speed and quality of the ADC input than how many volts or what type of system it is, anyway.
