Maybe also something aline the lines of:

inline fun <reified T> Bundle.parcelable(key: String): T? = when {
  SDK_INT >= 33 -> getParcelable(key, T::class.java)
  else -> @Suppress("DEPRECATION") getParcelable(key) as? T
}

Over to platform owner for consideration.

Yeah, we want this, but with b/240585930 we might only want to introduce this for U :(

also bugs me about Parcel.readParcelable. if ya gonna nag me in a gazilion places through my code at least give me a nice way to resolve it. these 'blah is deprecated' msgs for code that works on my minSdkVersion just kill me. sticking an if or a supress on every second line of my code is just ...

a little comment about the above kotlin inline fun, I need both kotlin and java solution.

Re #4, I think Google should offer this even if it's only going to work on U+ because right now the original APIs are deprecated and the replacements are not safe to use.
