I totally agree with Laurent : this is a very bad regression from my point of view. The community modules need this feature to "migrate" existing data when a module is installed which e.g. computes the value of a new column from the values in existing record rows. This typically needs to be done only once at module install time, and it is a waste of ressource to require these data migration actions to be performed in init which means an extra call at each start of the instance (and maybe even at each start of a worker?), which could mean a query over several 100k of 1M of rows.

Please revert this change, which is useless and harming your users.
