What's different today really is the LLMs and coding agents. The reason to never rewrite in another language is that it requires you to stop everything else for months or even years. Stopping for two weeks is a lot less likely to kill your project.

In Ladybird's case, tests they could rely upon.

He's still right if you don't have good automated testing and you lost most of the original developers (or you don't have other seniors ceva familiar with the domain).

		Hah, yeah if you don't have a comprehensive test suite any rewrite will be a disaster - step one is to get the test suite up to code.
