blossom imo as a protocol is garbage, as it tries to consolidate management (upload/delete/list) with retrieval of blobs

it is a big pain in the ass for scaling, look at any service and you will see cdn domains are separate from upload

blossom also makes no attempt to allow media optimization, and I believe it is an acceptable tradeoff to sacrifice integrity for reduced data usage if you can turn it off as needed

blobs should be identified by nostr event IDs, meaning you get metadata for free, and if a user wants their blob gone, they can issue a delete event and send it to all hosts

rehosting content becomes an explicit action
