Many years have passed and I would guess there isn't much reason to ever have OTF disabled. Does anyone still have a use case for this? If not, why don't we just make it permanently enabled? And then use the project properties icon in greyscale down in the status bar (which I still find pretty convenient to have there).

Big +1, for these reasons:

- OTF off results in confusing and often misleading measurements - see
https://github.com/qgis/QGIS/pull/3992
- There's no performance penalty associated with OTF when no
transformation is required - everything is short cut so no projection
is done
- If user's really want to display a layer in a different CRS to what
the layer has, they should just manually select a new CRS for that
layer in layer properties.

Besides, these buttons open the CRS tab in project properties, which uses another Icon (CRS.svg). So, for consistency and user's recognition, it would be better to use always the same icon when we are referring to select a CRS.
