Amen, and please don’t rush with the decision on the MCU (Attiny 25+).
The BLF X6-SE v2 & X5 should be once in a livetime lights - they already look like that, but they also need an adequate UI (MCU/driver).
We (BLF) should be striving for the best and the Attiny25/45/85 FW Development Thread already shows that this is the route to go.
Especially in SS/Cu lights without mechanical lockout (no anodized caps/threads) I really would like to see security features like thermal protection or an electronic (UI based) lockout switch to prevent unwanted accidents.
Just make it awesome! 
Best regards!
