I think the “bad” typing behavior for those stretches has a bit to do with PC gaming. In the old days of CS and other games before voip, T was all chat and Y was team chat. So my left hand was used to migrating to that specific key very quickly to open a prompt as my mouse hand transitioned over to the keyboard. As a gamer on a split keyboard, it’s usually fine, but sometimes I wish my left half had an extra column of keys.
