### When to optimistically import blocks
A block MAY be optimistically imported when either of the following
conditions are met:
A block MAY be optimistically imported when
`should_optimistically_import_block(store, current_slot, block)` returns
`True`. This ensures that blocks are only optimistically imported if either:
1. The justified checkpoint has execution enabled. I.e.,
`is_execution_block(get_block(get_state(head_block).current_justified_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, block) == True`.
1. The justified checkpoint has execution enabled.
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.
