I do not really understand what you mean when you say "worry". This board is a HAT or Shield for Raspberry, without it, it is not able to operate. PPB is let say a stand-alone product.
The moonlite focuser interface, for example, is something that I was hopeful to not have - no use for me, can be done via the Pi.
Regarding the focuser, the target (basically the recommendation was) is to have a stepper output, means the currently existing Astroberry focuser Indi driver would be possible to use with this board.
So I am working on integrating a DRV8834 driver on board.
I guess the price point would be the key
I am also working on to get a price for machine populated boards.
The current mechanical design is based on to use standard aluminum extruded housings, this Argon One type would require a complete redesign, and the pre-cuted connectors (HDMI, USB-C ...) are useless for that design.
