I have no problem with this but is it a good idea to run self test
with a different version as the target one?

What about Ross' suggestion:

Question: If this is accepted and works properly - could we get rid of
vte-native then?

Let's decide some option: I really would like to close this and I have
no problem with either way - gnome-terminal can wait. Gnome stuff just
hobby to me and for test I can add recent vte in my personal
meta-verse.
