   Because Ada 83 did not.

   Seriously, there were several proposals for extensions to the
variable name syntax discussed at the Salem, Massachusetts meeting.
After several votes, straw and otherwise, there was no clear consensus
on what to do.  (Choosing between options including adding underscores
at the end, treating underscore like another digit, or another
character, allowing leading and trailing underscores, etc.)  Since
there was no clearly acceptable alternative, no change was made.

   If we had been using a different voting procedure, we probably
would have ended up with the most change that a majority found
acceptable.
