Wait for all LSPs to be installed in headless mode

[pose]

Is there a way in --headless mode to wait for all the LSPs to be installed without having to manually specify each of them? I'm using:

nvim --headless +Mason +"MasonInstall typescript-language-server" +MasonLog +"w! mason-install.log" +qall

but that doesn't work if typescript-language-server installs faster than the rest. I tried waiting for :Mason alone, but it's not blocking.

Thanks!

Hey! :MasonInstall should run in a blocking fashion if executed in a headless environment (i.e. the command only yields back once all packages has finished installation).
