Composer install is failling

The tome module does also use submodules. The difference is that tome.info .yml is empty. But the composer result is a little bit strange where only the main project is marked as dev and composer seems to install version 1.12.0 (the current stable) :

 composer require 'drupal/tome:1.x-dev@dev'
./composer.json has been updated
Running composer update drupal/tome

I had over seen "minimum-stability" setting and was than confused about related issue on tome module which is still confusing.
