There is an equal need between stability and new features. MSFS needs to be viable for MS to continue it’s development, and part of that means opening it to new platforms, adding new features and growing it’s userbase.
I fully understand you and still deal with weird bugs from ages ago or even newly released ones. Yet we cannot stop the sim from potential growth or it will stay hidden in a small niche and return in the same states as last gens.
There has been so much work to get us betas to test, provide feedback on those features and get add-on devs onboard to make sure things go smoothly. I don’t think anyone here (the community, Asobo, MS) wants people to have a bad experience on purpose. It’s just the usual balance in time, money and quality.
Comparing from a year ago to now, I experienced very few CTDs, and have been impressed by the Sim’s stability. There is still some improvements but we are far from the times of SU5 or other major issues we had in the past.
