As a long time linux user i find it normal to only install apps through a package manager (essentially the same) but you have a defined API for package sources and can add sources as you like. that would be the best solution. manually installing apps IS risky, and opens the door for malware and incompatible packages, but if you have a trustworthy package source that your packa manager can varify its packages against it gets way better.
