I don't like this. the welcome login screen should be easy to use for non-techies and advanced options should be hidden in a separate screen for tech savy people to use.

That's exactly how it is in this PR. The screenshots above are what's shown when Add Account (advanced) is selected from the settings. Normal Add Account is still the same as before.

What this PR does, is basing Add Account (advanced) on Add Account instead of Account Edit
It feels more natural this way.
