Why don't use the fallback as well here ?

because if wrong coordinate are given as input, we will end up here (among other cases). And I didn't want to run a proj4 call on malformed coordinate, as it would require another try...catch wrapping
Using proj4 isn't accurate enough on a geodesic point of view, as the conversion isn't linear. There's a backend service that does the computation in a proper manner, so that's what is being used here when showing a LV03 value in the location popup. Tracking the mouse position while moving the cursor can still be done with a simple matrix transform, it's "good enough"
