Nope. It's neither necessary nor helpful. Just ground the OE.

It did say that OE doesn't affect the flipflops

You are basing that on obsolete information. The X16 uses addresses $00 and $01 for banking control freeing up the VIA for better uses.

To be fair, "obsolete information" is the information in the master branch of the CommanderX16 Documentation GitHub repo. The Readme.md does not hint that the information is obsolete. The zero page RAM/ROM banking documentation is in the board_r2 branch. The emulator master branch still uses the VIA for bank control and the x16_board_r2 branch of the emulator has been dormant for 8 months and is now behind the master (notably the latest SD card support appears to be missing). From what we've been told something is wrong with the r2 board and an r3 prototype is being planned - it isn't clear that the r2 board documentation or emulator is anything that could be relied upon. By all appearances, the obsolete information is the most up-to-date information one could expect to use when developing for the X16.

The README on the master is to support the current emulator. If you use 0/1 it will fail in emulation. So, unless you have a physical board, this doesn't help you. Once the emulator is updated to reflect the latest hardware changes, then we can worry about what's "obsolete".

However official announcements to the real hardware have been announced and that is the relevant and current data.
Is that true? Flipping through the official announcements the closest I see is a short reply on the second page of discussion to the announcement that the second prototype boards have arrived. Isn't that obfuscated for an official announcement? I'm not trying to just kick dust here; it feels like even highly competent people are going to have difficulty finding non-obsolete information. I'm an engineer who has worked in, around, or close to VLSI and board design at Intel and Microsoft for nearly 20 years so I like to think I'm pretty competent at picking up on these things and I only knew about the change because Kevin mentioned it in the New Year's video.
