Yeah some stuff hasn't been migrated yet but it's pretty rare in my limited experience.

Regarding your devil's advocate example, it's obvious a power user (i.e. tax pro) will have different needs than a layman like me, and it's clear that the sites are built for the latter, which makes way more sense as that's like 99.999% of the users anyways. The power users are probably so rare that just forcing them to phone in makes sense.
