Oh, the mechanical keyboard hobby has a rabbit hole for damn near every preference you've ever idly entertained for even a moment. There's an antire category of boards "Alice or Arisu" that does a similar split, though only a few have any slope along the left-to-right axis.

Then here on lemmy there's !ergomechkeyboards@lemmy.world which is a little corner of the ergo community. They are NOT fucking around with their typing devices.
