Re: [development] Why is Block table delta field only 32 chars?

Absolutely. We should change the delta (what does a block ID have to do with "delta" anyway?) to strings in D7. This would also pave the way for a hook_block_alter and other nice improvements for the block system.

and if it allows to have human readable css, this would be even nicer
