Lerna is defunct? Can you link any blog post about it? I thought the JupyterLab team was using that for their monorepo. I do not like the prospect of having to use a TS/JS specific build tool, because of wanting to use monorepo, but fortunately, I did not yet have to do that, as I only ever developed extensions, and did not fork JupyterLab, to change anything core. Lerna and the whole setup brimborium is definitely something that scares me away from even trying to change things in the core.
