Truename reserved DOS command

[Tails]

Has anyone known about the TRUENAME command in DOS 6.22 (and lower maybe)? It worked up to Windows 98 (I have not checked others) but it was removed in Windows XP. Why was that? The command does seem useless, but it does have a few neat features like displaying parent directories without switching.
Truename. = current
Truename..=parent
Truename...=grandparent
etc.

TRUENAME is a native, internal command in Command.com; however, Windows NT, 2000, and XP do not have that file in their root directories.

If you would like to add it, take the following steps:

1) Pull up a DOS prompt by using Run from the start menu and enter "command" or "cmd";

2) enter "copy c:\winnt\system32\command.com c:\" and press ENTER.

So Windows NT/XP do not run command prompts with their internal commands from command.com? How about batches? Because it is an internal command afterall and all the other things like copy etc, the well known stuff is present.
