Suggestions

Sometimes you want mobs to be able to break certain blocks but not target you trough them. So you only want them to break them if they previously detected you and you bloqued their path or you have another mob that alerts them, etc. Specially if you set all blocks to be breakable.

this would be very taxing on performance. vanilla just has either ignore blocks or not and changing that would break more than it would be worth it
