[Feature] Show full frame equivalent focal length instead of actual focal length

I have searched the existing feature requests to make sure this is not a duplicate request.

The feature

A photo captured from a phone at 1x zoom would display as 6.8mm, in the iOS photos app it would display as 24mm. I'm not exactly sure what anyone would do with seeing the real focal length when most people tend to compare using full frame equivalents. Another example, a photo taken from my Sony APS-C camera displays as 100mm when the full frame equivalent would show as 150mm. Always displaying full frame equivalent focal length would allow easier comparisons between cameras.

In exiftool I can see that the field 'Focal Length' displays the real focal length of the cameras (6.8mm and 100mm). There is also a field called 'Focal Length In 35mm Format' which displays the full frame equivalent focal length for both cameras.
