Unless civet's compiled output is hard to read you could always just check in the compiled Typescript source and continue from there if it gets abandoned. Not much of a risk when the migration is built in by the way the tool works in normal use.

The compiled output seems pretty clean, but isn’t necessarily what you’d write by hand. e.g. adds things like anonymous functions called immediately, when you’d probably just write a named private function, that sort of thing.
