I don't really see the problem with no removing your character from their screen. At some point you need to stop bickering like children and just move on. Square Enix are giving all players on all platforms the ability to blacklist someone and not see them. Likewise, you can remove them and all their alts from your estate. This is an entirely reasonable solution and doesn't require Square Enix to babysit the community. I've also seen some people complain that blacklisted players can still join your duties via the duty finder. If you honestly expected the developers to completely rewrite the duty finder algorithm to add tons of complexity for each individual blocklist, that copium must be some strong stuff and I want some. Besides, if these people are actually harassing and trolling in duties you can report them because it's already against the terms of service. The only thing I do want Square Enix to add is the two-way removal from the friends list which is standard functionality on literally any other game/platform.
