I do not really see what is "convenient" about this form factor.
For me, any of such boards where the pins do not fit on a 2.54mm grid, is either an (nearly) instant dismissal, or a rework of the PCB (if available) in KiCad to make it fit such a grid.
Boards like this can be nice for quick projects on matrix (vero) board, or experiments on a breadboard. If that does not fit, then it's usually not worth bothering with.
