Your absolutely right, DOF is massive on a 21mm.
The truth is, if you cant be bothered with a bit of guesstimating, wide angle on a RF is not your thing.
The size difference between the Zeiss 21 and a AIS Nikon 20/2.8 is null.
So the point of size is really a dead end, subjective at best, and prone to dragging out long debates with no avail.
Your R4 is the best option you have.
