dgozman: is this time to instantiate inspector_protocol in chrome/? But for now,
for better readability, do you mind introducing method per command with the same
signature?

GetWindowForTarget
GetWindowBounds
GetWindowBounds

etc.

Done.

This is nullable, no need to run getIndexOfWebContents when it is null.
