I've almost done with D version of [Sciter](https://sciter.com)
SDK.

Is it interesting to anyone in principle?
Just in case:
Sciter is an standalone and embeddable engine that includes:
* HTML5/CSS3 UI runtime;
* JS (QuickJS, ES6 compatible) with built-in native JSX, React'or
and persistence.
* GPU accelerated rendering engine (over DX11/DX12, Metal,
OpenGLES);
* OpenGLES implementation (and its JS version - WebGL):
* Windows and MacOS - over built-in ANGLE;
* Linux - native;
Platforms: Windows (XP...11, x32/x64 and ARM64), MacOS, Linux
(over GTK4 or Wayland or X11, x64 and ARM64).
Sciter SDK for D provides:
* Access to Window and DOM trees;
* Ability to write in D native DOM element controllers;
* Ability to extend JS runtime by D resident functions and
classes;
* Ability to control and handle in D all resource requests;
* Native access to Graphics API: Canvas-like 2D, OpenGLES;
