During the installation procedure of a module one may create some fields and corresponding instances and attach them to a content type. What is the best practice to clear up what we have created after module uninstallation?
It seems that removing fields created by a module is not yet implemented in D7 (see
field_modules_uninstalled docs.). What would be the best approach then to remove module fields?
comment module removes the field upon uninstallation (see here).
