This does make sense from a "crafting great software" perspective.

But building three separate codebases in comparatively niche GUI frameworks full of platform-specific quirks when you could achieve 95% of the quality with a single JS/TS codebase comes across pretty terribly as a business decision. It's hard to justify what is likely a 10x-ish cost multiplier with "it uses less RAM" or "the scrolling feels more natural". While large companies can afford it, the cost-benefit still doesn't look good to them.
