In search of the ultimate Devo7E

Though I see your points, and those are even valid, it would mean that we loose compatibility with the stock firmwares.
While it might not bother you, if I were a newbee, and that would mean it is no way back to stock, I would definitely not dare to try deviation...

What is wrong with the DeviationUploader?
While some users apparaently have issues going back and forth, it is certainly cross-platform, and generally has worked for anyone who has approached me about it.

The problem with any bootloader ther than the stock one is that it would take some effort to get the screen functional. That might not sound important, but on a transmitter like this, wondering whether it is functional or not, it is reassuring to see a familiar logo giving you assurance things can be made right again.

I think there is nothing really wrong with the stock bootloader. On the 7e/f7 the one benefit of a different one would be smaller size. squeezing another 4kb (or even 8kb) would be a huge win for those transmitters. But I don't think I could convince people to change their bootloader (while I can provide a ROM to upgrade the bootloader, it could easily result in a bricked Tx if used improperly). Expecting users to have an STLink is probably too much to ask.
