Additionally it is quite possible to reconfigure the editor, TinyMCE, to your own liking. Info on that here: http://wiki.moxiecode.com/index.php/TinyMCE:Index
I don't think that it is a step in the wrong direction. Not everyone uses ZEnphoto as a pure simple gallery, there are even "real portfolio" sites out there. It should be left to the user if he wants plain text or something else.
We will see that we get the toggle button into that like on Zenpage, too.
