Why our reviews don't measure transittance or T stop ?

It doesn't have to be a camera sensor although I don't see any major problem with using one. Any suitable light detector could be used.

If that happens, then for sure some way around would have to be found. I recall EF lenses can be forced to a given aperture by using DoF preview and disconnecting the lens in that state for example. I don't know how other lenses might react to similar.
