Don't be so dismissive. Apart from anything, that breaks one of the HN guidelines for discussion.

Not having access to built-in and user-defined (Applescript/Automator) Services is not trivial; these are a powerful part of what makes macOS unique and a major reason why I continue to use macOS. Their lack of availability is entire down to using faked-up menus rather than proper widgets.

Having widgets behave improperly is also an accessibility issue. There are multiple accessibility APIs built into the system that practically every macOS app built using Cocoa or Carbon hook into automatically; apps that use non-native widgets that don't take enough care to (a) perfectly emulate the behaviour of native widgets or (b) sufficient expose themselves to the built-in accessibility APIs not only make for an unexpectedly unpleasant experience but also potentially are showstopping for people with disabilities.

> But to my eye they look damn close to native and they seem to work perfectly fine

In other words, it's not a problem for you, so it shouldn't be a problem for anybody else.
