I've stated at length why Disney wouldn't want to do this in the 4K thread. Now, why they might: canon.

That's the one thing that'd make them pause. Now that there's apparently a story group, there's certainly a question of which version they consider canon. Right now it's the SE. But with the OOT release likely impending, and with people like Rian Johnson being the main authors of the new continuity, I wouldn't be surprised if there are some conversations about changing that. But then what, the OOT is canon and the SE isn't anymore? Would they want to change their minds? Would that switch actually change anything, continuity-wise?

Probably not. But if the quandary really gets under their skin, we could see a new version. Ultimately, though, I think it's not worth the effort and most people will probably say "who cares" anyway.

What's most likely happening is that the ST will be written so that either will work canon, making no mention of anything specific in the SE or OOT. Unless they make a Han shot first joke.
