[aprssig] Why only two symbol tables?

In the protocol document it says, "The character after
the latitude "N/S" in an APRS position report is a 
TABLE character and the character following the
longitude "E/W" is the APRS symbol character.  The
TABLE character selects one of two symbol tables or
may be used as a numeric overlay over some symbols as
follows:"

What is the restriction to using only "/" and "\"
based upon?  I ask because this seems to be an
interesting place to allow for expanding to more than
two possible tables of symbols.
