I can't reproduce that behavior on my Debian testing.

For me there is. If I choose Left Super as the Compose key I can confirm 
it instantly this way:

$ gsettings get org.gnome.desktop.input-sources xkb-options
['compose:lwin']

And if I disable the Compose Key control:

$ gsettings get org.gnome.desktop.input-sources xkb-options
@as []

I don't think "compose:none" is a valid XKB option. And you really 
shouldn't need to do that.

Similar indeed, but not same issue I think. Before I added a patch as a 
fix of #1027003, there was no way to disable the Alternate Characters 
Key control. But a way to disable the Compose Key control was and is 
present via code which has been committed upstream.
