If the developers want to look at making a work around that will allow your mod to work with WOFF3, guess is entirely up to their digression.
I totally agree. However, although I have alredy bought and installed WOFF3, I would continue to play WOFF2 just because I have the possibility to modify campaign missions and adjust them to fulfill mission objectives and to be more historically accurate. Just my 2 cents. I made this editor selfishly for my personal use at first with above in focus and I do not force it to anybody.
Since other forum members expressed interest, I released this info to community.
