> Feature toggles and configuration options are modern programmatic techniques to easily include or exclude functionality in a software product. The research contributions to these two techniques have most often been focused on either one of them separately.
Really? How can there be research contributions about "feature toggles" and "configuration options", and are they really really different? Sounds like a bullshit research field to me.
Nice dimensional breakdown of concerns in this proposed Model of Software Configuration v2 (MSCv2).
Is it difficult to write that one is build-time and the other run-time?
Actually, there are four binding times involved, but perhaps they differentiate the two approaches?
