Duplicating bound blocks maintains the connection to the same meta field – both blocks stay synchronized because they reference the same underlying data. WordPress recognizes single meta fields and prevents duplication even with multiple bound blocks.
Unregistering meta fields doesn’t break existing bindings but displays the meta key name instead of resolved content. Re-registering the field restores normal functionality without data loss.
Changing binding references in code affects display but doesn’t damage existing meta data. Post meta exists independently of block bindings – the blocks are just an interface for editing the underlying data.
Removing bound blocks has no negative impact on stored meta data. The metadata persists in the database independently, and bindings can be re-established with new blocks at any time without data loss.
