"dispatcher" is a "delegate" is odd. Why not just say that it sends messages
received by Blink to the browser process, using the Mojo WakeLockService?

Done.

~WakeLockDispatcher() override = default;

This produces "[chromium-style] Complex destructor has an inline body." error.

Done.

no "override" for Blink API implementation. Use "virtual" instead.
