Any MAF that can accurately meter the air going in to the engine is perfectly fine. Its original application is irrelevant. If anyone tells you different they're probably just ignorant.
Others may have different opinions but I don't personally see anything wrong with them.

20 years ago people relied on calibrated MAF's since there wasn't a whole lot of support available for tuning the ecu's. At that time it was "ok" to have drive ability issues since that's basically all you had to work with people knew it was to be expected.
These days there's no reason to rely on a calibrated maf in lieu of properly calibrating the ecu.
Calibrated mafs cannot adjust cranking pw nor dashpot nor startup enrichment nor startup air compensation nor commanded lambses nor accel enrichment, transient enrichment, adaptive logic, idle control, spark tuning etc...
All a calibrated maf does is scale the airflow as detailed in the maf write up. Thus that's correct spark is increased for a given condition since calculated load will be lower.
If it were truly that easy tuning wouldn't exist.
