Version 1.0.1 of hpack-convert not working out of the box?

[typesanitizer]

Is hpack-convert supposed to just work when used on a project?

Example:

Initial commit -- has sixten.cabal and no package.yaml -- compiles fine with just stack build.

Next commit -- used hpack-convert and compilation fails because of wrong dependencies.

Fix commit -- manually edited package.yaml so that the project compiles (although it generates warnings now, which I don't fully understand but yeah, that's one more thing which is different).

Did I miss some step in between?

It's supposed to work out of the box. Will have a deeper look at this case later.

would be a useful tool - why abandoned?
