Limit number of attachments
I could have sworn there was an option for this, but I can't find it.
Users can attach upwards of 10,000 media attachments to a post:

There should be a way to limit the number of attachments a user can submit with a post, as well as strip from federated content.
This is a problem because it slows down the UI, creates unnecessary database bloat, and is potentially very harmful to implementations that post-process attachments.
