The task of rebuilding the game engine in the way, I described above, is virtually equal to creating a new game engine from scratch.
Looking at things realistically, doing this was not an option for Oleg's team from the very beginning (original IL-2 release).
They did their best to support user's creativity by adding 3rd party models into the game for free themselves. But now, it's over, as every thing in this world ends, sooner, or later.
While doing so, they should understand and remember, that when distributing their "mods", they, in the most cases, redistribute a part of original game without permission of it's original author. Which, by all international and most national laws is a violation of Oleg's intellectual property, no matter what the modders may think, or say about it.
Obviously, it is doubtful, that anyone would be prosecuted for this, but in my opinion, distribution of mods (in the said above regard) means showing disrespect to Oleg, his team and their work. So, I don't see any reason, why Oleg, or anyone from his team should show respect to the modders. Particularly, when their work is way far from quality standards, we choose for ourselves.
