Why minSdkVersion on Android build is set to 22 in Capacitor v4?

[joshas]

Just upgraded to Capacitor v4. Migration went smoothly, but after update I noticed that minSdk version on Android was increased to 22. Is there any specific reason why it could not be at least 21?

It would be interesting to learn if there are some specific differences between API 21 and 22, that prevent former from being supported. I always considered Android 5.1 being only small "patch" update with no major API changes. And I have a target device with that old Android 5.0 version to support, it's very useful for testing worst case scenarios, as it is my least performant Android device.

While Android 5.0 is a year older than 5.1 and only brings additional 0.5% of Android devices (to total 98.6%), it would be useful to keep it supported, until Google officially ends support.
