There are 2 pathways to switch from VE to wikitext, and they now navigate the user to different URLs (this didn't happen prior to the bug fix).

If you start in VE editing mode, and use the "Edit Source" tab to switch to wikitext, you end up at:

On other hand, if you start in VE editing mode and select "Switch to source editing" from the Page Settings drop-down, you end up at:

Is this the intended behavior?

The change to the primary entry point isn't explicitly intended, but I don't think it's the end of the world to push people towards the canonical (and simpler) URLs.
