androidx.startup includes the following two rules:

# It's important that we preserve initializer names, given they are used in the AndroidManifest.xml.
-keepnames class * extends androidx.startup.Initializer

# These Proguard rules ensures that ComponentInitializers are are neither shrunk nor obfuscated,
# and are a part of the primary dex file. This is because they are discovered and instantiated
# during application startup.
-keep class * extends androidx.startup.Initializer {
    # Keep the public no-argument constructor while allowing other methods to be optimized.
    <init>();
}

The -keepnames rule is subsumed by the -keep rule and can be removed. (Also, I would have expected this rule to be redundant in the first place, since aapt should generate keep rules for classes referenced from AndroidManifest.xml?)
