Because of the nesting of our typer apps, we end up with a weird situation where one has to specify a final command, when intuitively we would like a default. E.g. seq2rel-ds preprocess <command> main. Ideally, we would like to be able to drop main, with the assumption that this is the subcommand we want if no other subcommand is specified. I have tried to figure out how to to this with typer with no luck. Keep an eye on this issue in case it is ever resolved.
