No. I think it works to hide the distributed nature of the fediverse, and works to make things that are inherent to a distributed model seem uncanney and broken.
It also strips some value out of the 'local' experience, communicating that each Mastodon-based website is the same as any other, and presenting something that looks like a dumb terminal, rather than a stand-alone website.
Ultimately, I think it's bad for the fediverse.
