## When to optimistically import blocks
TODO
A block MUST NOT be optimistically imported, unless either of the following
conditions are met:
1. The justified checkpoint has execution enabled. I.e.,
`is_execution_block(get_block(get_state(head_block).finalized_checkpoint.root))`
1. The current slot (as per the system clock) is at least `SAFE_SLOTS_TO_IMPORT_OPTIMISTICALLY` ahead of
the slot of the block being imported. I.e., `should_optimistically_import_block(current_slot) == True`.
