Me! I was a Dvorak user for around 6-8 years, but switched to Colemak mod-DH. I found it to be worth it. Colemak mod-DH is more ergonomic for ortholinear keyboards, less "alternate hand" keys, more balanced left/right hand ratio, and overall (for me) more pleasant to use.
I have a Moonlander and have it totally tricked out so I have no problem with qwerty hotkey locations. It's basically just the time delta to grind a new layout. When I learned Dvorak around 2009, it took me about a month to reach parity. It might be even faster this time around since I'm constantly messing with my layout with small tweaks and having to relearn muscle memory.
Also if you aren't using some kind of layer scheme to map things like ~./()= up/down/left/right to home keys, you are really missing out :p
