Is there anything that was broken by the lack of this line? If this code didn't compile, couldn't we detect it with an end-to-end test that runs package init with this template and then swift build?

Yes, we were generating the import XCTest without any whitespace between it and the previous statement, leading to broken code.

In theory yes, in practice we cannot end-to-end test macros today because we can't download swift-syntax on CI and we also don't have all the necessary components in the toolchain to attempt to use that as a replacement.

Looks like macOS self-hosted is also hanging?

My guess would be that it's related to #7269?

Actually, all tests should have individual scratch directories, so it doesn't seem super likely for this to be the cause. Can't repro locally, either.
