There is currently a warning.  There is no definite plan I know of to
turn the warning to an error, or to disallow completly, for example 
by ignoring the @macro.  But I suggest that you anticipate any future
error or change and replace by a user-defined name.  In the manual, it
is said:

   * It is not advisable to redefine any TeX primitive, plain, or
     Texinfo command name as a macro.  Unfortunately, this is a large
     and open-ended set of names, and the possible resulting errors are
     unpredictable.

That being said, I do not have a solution for the @table argument
issue (and there is a similar issue with @itemize argument).
