Q: HD means 16:9, right?
A: The FAQ on the Blizzard page states that the graphics in gog is UPSCALED.
The gog description says the same (and a bit clearer) "aspect ratio-correct upscaling".
That means they made the picture larger than the original thumbnail resolution but you still have the 4:3 ratio of course!

Q: Why doesn't gog simply do it?
A: There is a video on youtube where a developer talks about D1 and how they implemented the graphics: Diablo: A Classic Game Postmortem (@20m 18s).
They made a bad design choice, kept it and had to add workarounds for moving and the AI (the game is tile based and calculates where you will be and draws your way "backwards" and stuff like that).
Long story short: they messed it up during development so you cannot have widescreen all of a sudden. Like ever - without reprogramming the game; that would require full access to the source code and a developer team working for a year. You would need to change all the workarounds in the graphics, in the AI, probably in the networking too. So it is a rewrite of the game, incompatible to the CD version.

If you don't want to (or cannot) touch the code, you would have to create some loader that starts the original game but somehow hacks the game to preload all areas around your actual 640x480 window, put them together to whatever your resolution is and draw that. (As Diablo creates random maps you cannot precalculate the areas as they did it in Baldurs Gate; though you might be able to do it for Tristram only)
It looks like the Belzebub guys did that. I opened the downloaded archive and saw several graphics libraries and an executable: Belzebub.exe (the loader), SDL2 (a media library), glew32 (a graphics library), libpng (a picture library).

Sorry, but you cannot expect the gog team to do the impossible here. They make the game installable and runnable, they don't rewrite the code.
Belzebub is a competently new engine.

Saying that widescreen would need changes to the AI and network code is a miss understanding. The quote from the video is about some inefficiencies in the render, but they actually do not affect the possible resolutions.

Infernerty is a mod that fairly unintrusively changes the resolution with out affecting any other parts of the game.
Words can not explain my frustration when I realized that there is no improvement at the game at all.
I've run both versions, classic and high-resolution support, and there's almost any significant or noticeable changes.
Even gameplay still limited as 1996...

My hope is that someday Blizzard will get inspired and do the same Capcon did with Resident Evil, a trully Remake! Everything new!

For now, this version doesn't worth 9,99 dollars... maybe 0,99 dollars...
Personally, i find the HD mods out there for Diablo to be pretty good, like Belzebub.. sadly those mods do way more to the game than just improving the graphics sadly..
For instance, you can't save and load at will.. basically they're mods that change more than visual effects, which is sad..

Have you tried Infernity? I just found it today and it seems like a very vanilla D1 experience just with some quality of life improvements. https://github.com/qndel/Infernity
