You can see my first build (blue) in several of these pictures following similar advice to OP's guide (looping diodes, etc), with one modification where I used copper tape for the columns instead of wires.
Then the first picture you can see how much cleaner the single-switch PCB ends up, and I can assure it was far easier to solder / strip / assemble.
I've found the happy medium with single-switch PCBs ("Amoeba" is a popular one), which are fast and easy to wire up. Most notably you don't have to do the painstaking row wire stripping -- just use a plain wire from one PCB to the next in the key matrix (or an insulated wire if you have to traverse other components, which still only requires two stripped ends).
I have a few pictures floating around from my build(s) if that interests anyone.
Edit: this still works even if the battery/signal icon isn't there, you just have to guess approximately where the new location for the 'top right' of the screen is, and swipe down there to get the control center.
Edit2: messed around a little more and I guess you can actually access notifications using this method, it doesn't feel very consistent for me though.
