If you're writing five apps, you're doing it wrong. A huge amount of probably any app can be contained in a common blob of business logic and wiring, with some native presentation on top. Yes, I oversimplify, but folks have been doing exactly that for decades. More work? Yup, even with a common engine it's more work than firing up Electron. That's where "do we even give a shit about what we're shipping?" comes in. If there's no pride in the finished product, well, Electron isn't going to save your product, either.

IME, the UI library idiosyncrasies are the pieces that take the longest to get right. Common business logic is super simple by comparison.

I keep seeing people claim this, yet most UI software I see really doesn't do anything that complicated. It's some basic database CRUD stuff and some basic algorithms, and then all the actual effort lies in making the UI feel good.
