Don't worry about Pine getting spread so thin that they can't support these devices. The reason being that they don't support them (from a software standpoint) currently! The brilliance of their business model is they are very up front about only producing and supporting the hardware. The software support is entirely on the open source community.
As far as the hardware, their support generally only extends as far as defective hardware. Think DOA battery/display/etc. If a particular revision of a device has a hardware bug, but is otherwise functional, they will tend to fix the bug in a future revision. Customers bothered by a given bug typically have to buy a future revision if it really bothers them. For example, I got the first public version of the Pinephone which has a USB-C bug that only works with dumb chargers. The next revision of the Pinephone fixed that bug and they offered a discounted board replacement for those bothered by the bug.
Their main target customers are (hardware and software) hackers who should understand what they're signing up for.
