I was interested in the Sideband Android app until I discovered that they closed ths ticket asking to be added to the #Fdroid repos, claiming it's too much work and not enough benefit. 😭

F-Droid reviews all apps in their default store to ensure they are really #OpenSource (or #FOSS or #FLOSS if you will) and looks for trackers. They also require a description of what changed from one version to another.

These are benefits that you don't get by installing an APK directly from Microsoft GitHub.

It's completely valid to say that benefit isn't worth the effort. That's a value judgement. To some, even a trivial amount of effort is too much. To me, it's a significant value, and if it were my project, I'd create a .yml file and submit a MR to FDroidData.

Now, the effort to make their build reproducable is a different question. That may be easy or it may take a significant effort. Whether reproducable builds are worth the effort or not depends on how much the project cares about #security. How much work it is depends on whether and other projects using buildozer have already done this. If not, it'll also depend on whether the builddozer devs are interested in helping their users do this.
