should the return type be  'const char* const'?

As we discussed, I think this should be allOf(...) so nothing will be logged if any logger is suppressing output.

Nit: this formatting is quite odd, it would be easier to read if the opening and closing parentheses were on the same line

Why not replace this with "ALWAYS_LOG(LOGIDENTIFIER, session.logIdentifier())"

> Source/WebCore/platform/audio/cocoa/MediaSessionManagerCocoa.mm:-159
> -    LOG(Media, "MediaSessionManagerCocoa::sessionWillEndPlayback");

Ditto.

Changed.

Agreed.

Updated.

>> -    LOG(Media, "MediaSessionManagerCocoa::removeSession");

Because it's already logged in PlatformMediaSessionManager::removeSession().

>> Source/WebCore/platform/audio/cocoa/MediaSessionManagerCocoa.mm:-159
>> -    LOG(Media, "MediaSessionManagerCocoa::sessionWillEndPlayback");

Ditto.

>> Source/WebCore/platform/audio/ios/MediaSessionManagerIOS.h:62
>> +    const char* logClassName() const final { return "MediaSessionManageriOS"; }

Whoops, nope:

> error: 'const' type qualifier on return type has no effect [-Werror,-Wignored-qualifiers]
