Yeah, as far as I’ve seen, that’s the vibe: Esperanto isn’t perfect, it can be improved, but it works and changing it would introduce confusion and would make it harder to learn.

I also sense this unease among the Esperanto-speaking community with regards to changing anything in the language. That allowing any one of the proposed changes will lead to a slippery slope of accommodating any and all proposed changes.

And then there’s the fact that not many of these changes have gained foothold amongst the community (perhaps due to the aforementioned unease in changing anything about the language).
