Yeah, that is quite a wonderfulness,
http://www.aprs.org/aprs11/tocalls.txt says:

      APRXxx  >40 APRSmax
      APRXxx  <39 for OH2MQK's RX-igate

APRSmax is Bob's own original APRS application. I just checked the
usage statistics for the past 3 months:


APRX1C    1
APRX1D   15
APRX1E    3
APRX1L   12
APRX1M    3
APRX20  171
APRX21   26
APRX22  106
APRX23   63
APRX24   55
APRX25   32
APRX26  275
APRX27  722
APRX28   23


APRX44    1
APRX46    1
APRX76    3

And here are the 5 aprsmax users for the past 3 months:

srccall  dstcall comment
N6GIW    APRX46  ....dDvs
KD4QIA   APRX44  Henderson Mountain
N3OZB    APRX76  isobar at verizon dot net
WB4APR-3 APRX76  Bobat work

I would suggest that APRXxx could be allocated completely for aprx,
and aprsmax would be allocated some other tocall if Bob is to continue
its development at some point.

It would be so much easier to specify that the tocalls either have a
specific single value (like APCLEY), or a prefix with a few characters
to specify versions (APRXxx). aprsmax is the only exception to that

Having the version digit range divert to another software is an
unnecessary complication, especially if it's only for the sake of 5
copies of aprsmax.
