> It's sad to see people be so nonchalant about potentially killing off smaller platforms like this.

Your comment is needlessly dramatic. The only hypothetical impact this has is that whoever uses these platforms won't have upgrades until they do something about it, and the latest and greatest releases will only run if the companies behind these platforms invests in their maintenance.

This is not a good enough reason to prevent the whole world from benefiting from better tooling. This is not a lowest common denominator thing. Those platforms went out of their way to lag in interpretability, and this is the natural consequence of these decisions.
