Still I have no idea why this pcb doesn't have a full length bottom row, and chooses instead a shorter hhkb bottom row ) aesthetics I suppose.
It's difficult to deal with the 0.75u spaces on both sides.
The L_Shift (2.25u) and R_Shift (1.75u) on the row above remain to be some of those more available Shift units.
HHKB JP has 2 sensible 0.25u dividers on the bottom role.
All these 60% boards with arrow clusters have their smart solutions: 1u R_Shift (HHKB JP & Filco Minila), "Banana split" 60% PCB, and this one.
If I really have to choose one among them, I think this one has a more elegant solution in my opinion. I believe I would enjoy the larger R_Shift compared to the 1u R_Shift of Filco Minila and HHKB JP.
One thing I would like to add is the L_Shift split to have a 1u + 1.25 option, instead of just the usual 1.25u + 1u.
