I've got resources for the various keyboard layouts on Github:

Some information on split and tenting keyboards can be found here:

However, switching keyboard layouts tends to be difficult for most people, and the gains are generally rather small. Many if not most users would be better off devoting the same amount of time to improving their touch-typing on QWERTY than to switching layouts.

Besides, people also use laptops and may not want to swap their keyboard.

Laptops are not ergonomic, and nobody who knows the facts will use them for long periods for precisely that reason. However, you can make them less damaging to your health by putting the laptop on a riser and using an external keyboard.
My own reality is I used a "ergonomic" labeled keyboard that I felt caused me more discomfort.
Of course there are convenience trade offs somewhere and laptops to me fall under convenience.
All that said, I fully encourage any mucking about with keyboard layouts. There are quite a few variables that can be tweaked.
When I use a regular keyboard, I feel hunched up in the shoulders with elbows held tight to my abdomen, by comparison.
