It's important to note that this isn't a dev response that is meant to directly address the issue in the OP. Someone else just saw that it was a dev comment in a related issue and linked it.
If you look at the linked thread the quote came from [1], the quote is actually answering a similar issue titled "Why are there nodejs files in my zed install". Judging by the response, the dev had interpreted the issue title as a "what does zed uses nodejs for" and not "why does zed downloads nodejs without informing the user" and answered accordingly.
There are more relevant links to PRs and comments further down the GitHub thread (the one in the OP) where the zed devs acknowledge that they are still thinking about how to best implement the UX for extensions downloading LSPs and whatnot.
