That's where I got my update/backup img from.
A mail was sent, but what if they all claim to be a 'official' or
'direct' store?

option 1:

      - description: A95X Z2
        items:
          - const: a95x,z2

  "^a95x,.*":
    description: A95X

or option 2:

      - description: Zkmagic A95X Z2
        items:
          - const: zkmagic,a95x-z2

  "^zkmagic,.*":
    description: Shenzhen Zkmagic Technology Co., Ltd.

I'ld rather prefer a short neutral name like option 1 just to be save. ;)
For the completeness there seems to be:
a95x a2
a95x a3
a95x f1
a95x f2
a95x f3
a95x max
a95x max plus
a95x r1
a95x r2
a95x r3
a95x r5
a95x z2
a95x z2 +

Any advice welcome..

Johan
