Not really, but let me tag some people who might (@danalbert, @srhines).

In either case, this change is obviously correct.

Per https://developer.android.com/guide/topics/renderscript/migrate, we are starting to turn things down as part of the deprecation. I reached out internally to the folks helping with that to make sure that we don't cause problems by deleting upstream code. I suspect that we'll be able to make more progress with adapting upstream soon. In the meantime, this CL is fine.

Rebased.
