Some of the reasons given would mean they wouldn't have implemented SSO in the first place, but they still did it. Adding merging functionality would be a similar situation to SSO existing in some regard.
If TurboTax is the more sensitive account that's halting this, then couldn't it could be a 1-way merge where you must use your TurboTax account as the primary account to then migrate the Mint account into it (while it's then not possible to do it in the other direction)?
