Location on existing events disapper

Periodically the configured event location on an existing event goes missing.

My hunch based on initial investigation is that the use of shared address info ( stored in the table `civicrm_loc_block`) is not intuitive to end-users and therefore when the end-user is creating a new event, its very easy to unintentionally break the location on an existing event.

Is there a way that each event can be directly linked to the civicrm_address table, where each address either a) has its very own address or b) Has some kind of "Shares address with" checkbox (like already exists for sharing addresses between contacts)
