One of those completely useless phrases...Personally I am against modifying TC to support this (unless you have better arguments )
What exactly would be your disadvantage when people wanting to echo something can do that without the need for cmd /k or a batch file?
Or what if someone wants to have a quick look at all variables? Enter "set" and there you go. What's the sense of hardcoding some commands when you can have them all? Where is your point?
Being against something is always the easiest choice, you don't need to argue at all then...
Writing batch files for all commands is an intelligent workaround for a TC design flaw but no solution.
Here is a list with all commands starting from DOS to XP, what OS supports them, their paramters and much more:
