It does make perfect sense to keep the default version clean. Most users will get mad when something gets broken, and you can’t risk stability or compatibility for experimental Windows support (it’s called DOSBox, after all).
That being said, personally I would love to see an additional setting, maybe called “experimental”, that’d be loaded with all available patches. I’m running DOSBox ECE on my PC for example, and prior to that ykhwong’s builds (until they got too broken).
Of course, a big problem might be to maintain all the code involved.
