> how much potential return would you get from this group?

This reads a bit like "these poor sods can't afford to pay for my app, so why bother", at least to me.

However even if a certain device owner subgroup doesn't represent a potential revenue stream, you can as a developer still profit from also (or even primarily) targeting their devices.

Apps that will run on lower-powered devices will almost necessarily be leaner, and as a side benefit will have less complexity, less dependencies, and, ultimately, less technical debt for you as the developer to manage.
