It's not so much a problem for me, because I can self enforce these limitations and stretch my spell slots between three or four encounters. But not everyone plays that way, and self imposing restrictions might ruin some of the fun for them. I really hope they do something about it.
I hope you know, as it currently stands, you are penalized on your relationships with companions by waiting to take long rests. Yup. Long rests advance certain companion story lines so if you wait, you miss out.
