The issue here is that LCC's like WN/Southwest use this extensively, and Delta uses it (or maybe stopped using?) for flights like ATL > LGA > ATL. So not sure it's going to change any time soon, nor if there will be restrictions on how it's used...
WN is different because as far as I know, a single flight number means a single aircraft. So you generally
can't misconnect. On the legacies they do this for marketing. It's almost always a change of plane/gauge - but it looks like a more attractive option in the search results ("oh honey, let's take this flight because we don't have to change planes") but is really a form of bait-and-switch IMHO for the layperson.
And single flight number turnarounds is also another story.
