Yup, seems like this is a good thing to add to the GeckoView API.

I've tried that but I can't get into full screen mode because it needs to be
started from 'short user triggered event' and I want to host HTML5 based game
inside my GeckoView and I need locked landscape orientation without user
interaction.
So I look for one of the following:
1) some way to trigger fullscreen mode from javascript without user
interaction
2) way to disable processing of event that notifies Gecko that device changed
screen orientation, I don't know where to look in the source for code handling
screen rotation (native code?).
3) mozLockOrientation documentation states that locking rotation is allowed
outside fullscreen in webapps so maybe there is a way of adding GeckoView as
another exception. It would make sense because Android interface components
doesn't rotate by themselves, their container (ie. View) handles that.
Opera Sphynx (a modded, embeddable Presto engine, née Oupeng) hacked
together a solution for this usecase using <meta name="oupengmobile">
tags [1][2], where the content attribute could be "landscape",
"portrait", "lockrotation", "fullscreen", or "game" (can't remember what
that corresponded to).

Not sure if a JS API is better than markup/<meta> (my personal
preference leans towards script), just pointing out how it's been done
before.
