How much I dearly hope we get proper deleted/alternate scenes on the Blu-ray. I’ll be disappointed if all this is just swept under the rug. TFA’s bonus material already felt too sterile compared to the Prequel’s DVD bonus material.
Swept under the rug is a possibility. TFA went through some big reshoots as well (though not even close to this) which led to the excision of scenes such as Maz at the Resistance base. So it’s possible LFL is taking a “pretend it doesn’t exist” course when it comes to deleted scenes negated by the final film.
On the other hand, there’s good reason to believe TFA is a specific case, where certain things that were cut they don’t want you to see, depending on how things play out in VIII and IX. It’s even less clear with TFA than RO, but I do believe the original intention was that both Rey and Finn were called to the saber, which then lead to a flashback explaining its journey (probably in place of the Force vision). Then Maz gives Leia the saber at the base and tells her it should be with Finn. I don’t know when Finn’s Force awakening was cut (either during shooting or in post), and I’m not sure if it was simply done as part of emphasizing Rey’s journey (with Finn’s to come later), or because it was decided Finn wouldn’t be Force sensitive at all. Either way, they don’t want us to know about it, so they cut whatever of that storyline was shot. As well, it is unclear how much in the way of Force abilities they want Maz to have, so they cut out her bringing the rocks down on the troopers, which is why the Han “Smoke?” deleted scene ends abruptly. Again, who knows if this is because they want to reveal her powers later, or because they don’t want her to have powers.
