Yeah this is a design change that can only be fixed on the client application side because there will always be a reason created by an instance for why they don't want X content mirrored to their site.
Couldn't you just sign up on an instancewho's sole purpose is to remain federated with every other (major) instance and then "add" that account which the client app maintains along with one or all of your other accounts and wouldn't that super easily fix this issue even though it would be better for rhe app to handle all that without having an additional account to maintain?
Edit: also, did I just roughly describe a "mirror" without even knowing it from the spirit of what I said?
