After discussion on Discord, given that the "V2" board is identical to "RGB", the proposed way to handle this is:

• Add an alias pointing v2 to rgb in the keyboard aliases file: https://github.com/qmk/qmk_firmware/blob/master/data/mappings/keyboard_aliases.hjson
• Move any non-defaultish v2 keymaps to rgb
• Delete the v2 files from the repository

I think that this PR should progress as posted. There is most certainly a third PCB on this. Electrically equivalent to the "soldered" variant, but hotswap in the V2 (and not per-key RGB) ... as per the vendors own webpage on this product:

That they ship this product with the f/w of the "soldered" firmware is less relevant since that causes confusion with users when they attempt to customise with QMK (or VIA for that matter).

This is a (mostly) community driven project .. so it would make sense that the users make their own experience easier ... that some individuals in the vendor are less informed on firmware should not impede us from leverage this great platform.

Putting this on hold until we get an indication of the situation from @moyi4681.
