I have been mulling over 24+25 ownership since the last update on the 24mm release/previews and I agree it wouldn't make sense to have both, would need really then 24mm and 50mm 1.4s.
But since I like the 35mm "look" so much that is unlikely to happen in my kit bag.
So it's back to square 1, need an ultra wide 1.4-1.8 prime lens from Sigma!
