StataCorp developers follow the list. Thus your suggestion
was, or shortly will be, read by many of them. 

Now I am not a StataCorp developer, but I don't see that 
there is any need for implementing your proposal at all. 

The reason is that if you have a composite panel identifier you 
can map it to a single one in a single command line using 
-egen, group()-. Thus there is no need for a hit on -tsset-
and all sorts of associated commands, to say nothing of the 
consequences for help files, manuals, FAQs and so forth. Thus
the user can solve this problem by a simple operation carried out upstream
of -tsset-. 

This was already explained in the thread you reply to, although
for brevity I have deleted most of the long email you 
copied without editing.
