Just here to rant about 'S3 compliance' a little - I have no real awareness on the topic at hand.

Tangentially this is lamenting at the lack of choice

Last night I tried to set up BackBlaze (S3 'compatible') behind Mattermost.

This doesn't go very far when clients use/rely on headers that specifically mention vendorization

BackBlaze won't work with clients that try to send x-amz-sdk-checksum-algorithm, Mattermost taught me this

TLDR: S3 isn't always S3
