+ <summary>

+ Tracks flags and capabilities of enabled accessibility services. Recorded

+ every time an Android web content view first creates a virtual view

+ hierarchy, indicating that some accessibility service is running. The number

+ of emits of this histogram won't be as useful as the unique user counts. The

+ primary purpose of this is to guide optimization by determining what

+ capabilities of accessibility services are widespread and which ones are

+ relatively rare, because it's expensive to fully support the needs of a

+ service like TalkBack but there are many other accessibility services that

+ need far fewer capabilities.
