> Why and what you can't achieve from HIG?

I gave you examples, and you dismissed them because "vendor lock in is bad" and "I don't see what this has to do with native vs web".

There's no modal dialog on the web that conforms to any of the existing HIGs. And while you can implement one, the amount of effort is ridiculous. Compared to native.

And that goes for almost literally everything. For example, there's a reason 99.9999% of the thousands of dropdown re-implementations fail even the simplest of accessibility checks.
