I sympathize with reluctance to add new commands, especially when one is 
very similar to an existing one.

...but making a general feature (and completion-at-point is a general 
interface which we use in many context) more complex can be much worse.

TAB and 'TAB TAB' already do different things. Now, what happens if a 
third 'TAB' will switch the completion tale? The user will have to count 
how many times they pressed TAB now. Did I press it one or twice? If 
once, next press will pop up the Completions buffer, if two: switch to 
another completion table. What if I press TAB 4 times, what will happen? 
Or ok, I pressed TAB a few times, but forgot to count. Which completion 
table is it using now?
