I want to understand the consequences here: if merged as is, it would show an edit in studio link in courses where people are actually using an store-in-github -> import-into-studio workflow, right?  The link won't be useful in those cases, but it doesn't seem to be problematic either, so I'd rather not add yet another config setting just to turn it off.  As an aside, we're actively working on making all the different types of XBlocks work in Studio, and on changing to the version-tracking Studio backend, so hopefully many of the reasons why it doesn't work for some MITx courses today will go away in the next few months.
