Not sure about ‘bad form’ Matt, but I don’t think it is best practice. Clearly you can do a lot in a child theme than just add ‘rel=me’ into the header, such as adjust the CSS to remove lines etc. In the end, it works for me for now. I am not sure what others would say and I know that quite a few are critical of the SNAP plugin – not sure exactly why – I am probably a bit more pragmatic.
