They do exist in the USA.  So where they exist, then I think they should be
used.  They do it for VHF in the USA, so why not for UHF.

Just hold on.  NOWHERE is simply sending + or - a part of the FREQ spec.
Any packets that include that are not in accordance with the spec.

Neither of those are part of the APRS FREQ SPEC.  Only +xxx or -xxx are part
of the APRS spec where xxx is in 10's of KHz.  The standard offset is used
IF AND ONLY IF, there is NO OFFSET data in the correct format in the packet.
