Not just your two android apps, any program on your system that is aware of your waydroid installation could potentially use it as a path to escalate themselves to root, which is generally regarded as a bad outcome. If you don’t care about that kind of thing, or don’t think that could ever happen to you, that’s certainly within your rights to hold such a viewpoint.
The only reason why consumers like you and me get to enjoy free software on modern PC hardware is because of the expectation of open standards and interoperability set way back when the industry was still growing and computer users gave a shit (or rather, when only the people who gave a shit owned a computer).
Much to the industry giants’ enthusiasm, mobile hardware stacks were developed without this baggage, and so unless something fundamental changes, all mobile devices trying to focus on free software will be doomed to failure by abysmally poor hardware support and aging hand-me-down hardware.
