I started including this "date" in the file name when I realized that
in some cases there were different "dates" associated to the same
firmware version. I always recommend using the matching "date" when
both are available.

I don't think this is true. The [6] key + power-on messages are stored
in "aux" memory. I have never seen a "RESET" affect anything "aux"
memory (welcome message, 6+power-on message, band limits, etc.).

They will only be blank if they came from the factory that way or
someone uploaded a CHIRP image where they were set to be blank.

Yes they do. I've always considered them as being some sort of date
code ever since I got my first UV-5R back in early 2012.

Yes. BaoFeng (the radio manufacturer in China) could.

Every one of mine. Just to be sure, I just performed firmware RESET my
UV-82 and the 6+Power-On message was not affected.
