I don't blame them. That's exactly how I would feel!
That, or, it's easier to upgrade to a new JS version + let your transpiler figure it out, than to rewrite your code in some other language that compiles to JS.
I'm already fighting with people about integer literal separators not being supported in e.g. Vue and stuff, the more that's added, the more the community becomes fragmented, and I'm not convinced that transpiration (I hate that word...) is really paying off for us after all these years.
