Yeah, I guess that'd work if I had a couple of accounts, but since there a bunch of them, I really need proper import/export to feel comfortable with moving to it. I just know I'd punt the task of migrating everything if I have to go account-by-account to migrate away.

Considering that today it'd add work for me today, and future work, with no additional security benefits compared to my current approach, it just don't seem worth it.
