They do, probably, but realize that those layouts will lose some of the other characters (how many depends on the language) because there are a limited number of keys on the hw keyboard. Most, if not all of the non-English languages have more than 26 letters, for example. The letters you lose (or which may get hidden behind some function key combo) are typically special characters that those who only write letters to friends never use, but it's like having an amputation if you want to write something as simple as 'ls -l `find . -name "*.org" -print` | grep ^\$ |more' in osso-xterm. (by 'simple' I realize it doesn't look simple to non-commandliners, but stuff like that is normal for some of us.)
