"Instead I'd argue it's incredibly expensive and should be treated as such."

Using a cross-platform framework isn't incredibly expensive in time or performance cost. It's done by one-person projects and large businesses alike. There's issues but that's way overstating it.

Then, there were 4GL's like Lansa and Windev that made it easier to do than creating non-portable, native applications. Those weren't used for performance-sensitive code, though. Mostly business apps.

I wasn't being specific enough - I meant expensive in the most general sense. e.g. An abstraction is a cost not only in terms of (potential) performance, but developer headspace, etc, etc.

The right number of abstractions is very powerful. Too many any you'll sink under the weight of them.
