I don't think it's that they've decided here at the end to make Sklyer more interesting, they've just been trying to reclaim her as a sympathetic character for the sake of the story. I've zero doubt that Gilligan was well aware of how unpopular she has been with his audience.See now, Seasons 2-4 would have been so very fucking much better if they had made Skylar the reluctant woman behind the man. Rather than this "oh yeah, it's the last few episodes, I guess we can finally make skylar stop being so horrible and uninteresting". They couldn't have done it in season 1, but they could have started it in season 2 along with Jesse, and by S3 at the latest Skylar's character would have been worth watching. And it would have made Walt better too. He wouldn't have had to have been so deus-ex-machina flawless "I planned that all along!" all the time if he had a wife to bounce (even veiled) strategy off with.

It would have cost the "I am the one who knocks" speech, but one decent scene for far too many to count fast-forward scenes would have been a very acceptable tradeoff.
They missed it. They could have made her a smart frontier justice version of Carmella.
It's the same sort of thing that was done with Catelyn Stark in GoT. The writers started adding in all sorts of things to her personal story several episodes before the Red Wedding so that her death wouldn't detract from the shock and horror they wanted that event to have.
