Every single feature someone accepts into a code-base comes at a cost. That feature needs to be reviewed, tested and above all maintained and deal with any possible bugs that might arise from it. Especially open source developers only have limited amounts of time to spend on something. Investing time in this feature means not being able to invest time in something else. Accepting a feature that a few people might use, hidden away somewhere in the advanced configurations, might very well not be worth the trade-off to them, even though you personally find the feature valuable. It has nothing to do with a walled garden. Ultimately, if this is so important to you, you have the choice to fork and maintain it yourself and carry that cost. That'll most likely be a lot of work, especially if you want to keep in sync with upstream. But it might give you a better understanding of and appreciation for the tremendous amount of work and effort that goes into projects like these. Work that goes largely unpaid.
