+# If we exclude this, upload silently fails (Sentry swallows a NPE so we don't crash).
+# I filed https://github.com/getsentry/sentry-java/issues/572

+# If Sentry ever mysteriously stops working after we upgrade it, this could be why.

+# kotlinx.coroutines: use the fast service loader to init MainDispatcherLoader by including a rule
+# to rewrite this property to return true:
+# https://github.com/Kotlin/kotlinx.coroutines/blob/8c98180f177bbe4b26f1ed9685a9280fea648b9c/kotlinx-coroutines-core/jvm/src/internal/MainDispatchers.kt#L19
+#
+# R8 is expected to optimize the default implementation to avoid a performance issue but a bug in R8
+# as bundled with AGP v7.0.0 causes this optimization to fail so we use the fast service loader instead. See:
+# https://github.com/mozilla-mobile/focus-android/issues/5102#issuecomment-897854121
+#
+# The fast service loader appears to be as performant as the R8 optimization so it's not worth the
+# churn to later remove this workaround. If needed, the upstream fix is being handled in
+# https://issuetracker.google.com/issues/196302685
