The trouble with that is moderation. Presumably there exists some Nazi who has a Wordpress blog. If they're a particularly noisy Nazi, that could get Wordpress.com banned on a lot of instances, because the Fediverse's primary and easiest moderation route is nuking badly-behaved instances, and many instance admins are _particularly_ sceptical of corporate ones (some instances have _preemptively_ banned threads).

This way, every Wordpress blog is for practical purposes its own instance.

That said, the username component does seem unnecessarily unwieldy.
