Not sure about faster, but you could do something with overrides, especially pnpm overrides since they can be configured with plugins. Build a list of packages that can be replaced with modern stubs.

It couldn't inine them, but it could replace ponyfils with wrappers for native impls, and drop the fallback. It could provide simple modern implementations of is-string, and dedupe multiple major versions, tho that begs the question what breaking change lead to a new mv and why?
