Good point. I'm a big fan of the federation of different IRC servers, but also like have rich media embeds and drag+drop image uploading, even if that currently means being tied into the discord servers.
But I think this is only a problem from a UX standpoint. IRC has DCC, for instance, but it's a matter of building a client which e.g. inlines DCC "attachments" or displays images beneath messages with links. If IRC is truly "revived" there's a chance IRC clients grow or new ones emerge to keep up with "modern" IM systems, and IRC will still have more benefits than these (openness, ubiquity...)
For example, I might allow specific rooms that I know are moderated or specific individuals that I trust to push arbitrary data in to my storage. However I definitely do not want that to happen in a random room of strangers.
