> How to make sure that this module is installed if crm and base_contact are both installed ?

Maybe it shouldn't be an extra module, but the crm, sale etc. modules should be updated, so that they would check if contacts (or cities or some other usefull table) is used to store information in relational manner, instead of the old monolithic basic records?

Do installed modules prevent the creation of old obsolete fields in new databeses, i.e. so that the address table will not be created with fields for a person's names and email address (or have them migrated and removed) when base_contact is installed?
