This is only needed when vendoring.

This is only needed when vendoring.

Correct. I can modify the bootstrap script to only check it out if vendoring is enabled. Is that preferable?

[bjorn3]

I think so. That would cause less waiting on the download in case rust-analyzer doesn't need to be built.

[yungkneez]

Okay, it will now only checkout rust-analyzer if needed 😄
