Colemak user here, one of nicest things about Colemak IMO is that the ZXCV keys on the bottom row stay in the same location. I tried out a variant for a while that had XCDVZ and my brain could never get used to it. For other common shortcuts (Ctrl+T when browsing, Ctrl+F, etc) I didn't find it too hard; I guess some shortcuts are more muscle memory and others are associated with the letter in my mind.

I will say, having learned Colemak early on has made me give up on learning vim more than once for the same reason you highlighted -- I want to have my navigation on the homerow but the burden of remapping all of the keys without knowing what I'm doing was too high. I've heard that many people just use hjkl in the standard Colemak positions and don't remap keys at all, but that seems crazy to me, since they are spread all over and J is in the worst possible spot on the keyboard.
