Properly modelled combustion chambers

It's a small thing, but it's something that always bugged me in KSP and having seen the latest preview for the new engine models I saw the same thing occurring again.

That thing being a lack of properly modelled combustion chambers. In KSP, the inside of the engine bells either end in a point or a flat texture-less disc. The new engine models are already worlds better with a properly modelled fuel injector.
However, it's still missing one of the most important part of a rocket engine; the actual combustion chamber.

It's certainly not a major issue or dealbreaker, but it would add just that little bit of realism in how actual rocket engines work.

In the images below you can see the current model, where there's no combustion chamber, and the real life engine it's based on where the engine bell leads into the combustion chamber with the fuel injector at the back.

In any case, I do want to say that the current models still look amazing and I can't wait to construct some rockets with them!

I see what you mean. It's a minor issue, but that's definitely going to bug me now that I've seen it. You're not going to like the performance you get out of an engine with no converging section or throat, IRL.
