I already use Proton Calendar, I don't want another calendar installed. Stop pre-installing bloat and let the user decide.

With the switch to the Fossify fork in the latest update, all Simple Mobile Tools apps that could previously only be disabled could now be uninstalled - except the Calendar app. Why? How can I remove it? In general, I don't think any of these apps should be preinstalled with the OS. What happened to...

Where can I find the correct halium boot image to load with the Volla Boot Manager?
