I assume it will be done at some point, but it would be nice if the pinout card back had the same information as the other Teensy pinout cards, with the qspi memory pin layout (and the SD pins).
For the psram chips, it may be useful to maintain an online list of places that sell those chips, since there are only a few places.
And for the flash memory chips, it would be helpful to have a list of the known chips that work that are still in production (possibly having a list of the older chips as well). When I got my first flash memory chips for the audio shield, several of the chips listed were no longer in production. I don't know if it would worth it if PJRC.COM offered one of the chips for sale.
Obviously when the NAND support comes in, that will need a new paragraph.
I know the problem of having too many SKEWs, and of soldering the chips on to boards, but I imagine some users soldering skills are not up to SMT soldering, and it would be nice if there was a Teensy 4.1 with pins soldered on and with 2 chips (psram and flash). While I can now solder at least SOIC connections, I do recall one of the things that led me down the Teensy path in the 3.0 days was the board came with the 28 pins soldered in as an option.
