I just updated the PCB and that's pretty neat indeed !

So it looks like the protection diodes are a "feature" that can become beneficial if it is used creatively :-)

The Eagle file is updated as well and a PCB run is started, stay tuned !

That is looking good! The new PCB is now it is also simple to etch the new PCB at home.

Exactly !

I can't believe it's now so easy....

A new set of boards is in production now, might arrive in a month.

The only drawback I see is potentially inconsistent luminosity from segment to segment because these LEDs are not rated at such low current.
