Indeed, gstreamer updates go to staging.

I don't think that's necessary or even beneficial.  Drop it.
Ditto for all the packages referencing it.

Do gst-plugins-good really no longer depend on the base plugins?

Idem.

Ibidem.

Packages that only require some bad plugins and can exactly state which
should not be forced to pull in all of them.  The bad plugins are
explicitly named bad, because they're bad.  Enabling any of them beyond
necessity should be an active choice of the user.

My, what a perfect use case for gst-plugins/selection that would be. 
Note, that gratuitous media codecs are an additional attack surface.
