For us, I think it's time to move away from the film reference. It's a bit tedious and eventually it's going to "age out". "Full frame" is going to be equally obtuse because you'd need to know what that means.

So you'd swap one fairly arbitrary frame of reference...

Maybe a better "constant" is the human eye. Let's consider it a factor of 1. Surprising enough, that's been measured at about 43mm and a 55 degree angle of view.

...for another frame of reference that's inexact and open to varying degrees of interpretation.
I reckon we stick with what we've got - actual focal length within the system and then a convention that allows us to compare angle of view between systems.
