Maybe VSCode could show a little traffic light next to each plugin indicating its latency impact. What IDEs have going for them is that the features are generally constructed by people who know what they are doing and test them at the same time. Whereas a plugin could be written by anyone. Also there's a great "works on my machine" when it comes to performance: the plugin author will just test the plugin on its own rather than with a bunch of other plugins, so their performance target is artificially low.
