I fully agree.  If the weather format would be extended to add fields, 
then all receivers would need to be updated to parse the additional 
fields, fit them in their database schemas, etc.  This is not a good path, 
as this obviously would not be the last time fields are added.

With telemetry packets, each transmitter may specify whatever measurements 
they need, without the receivers needing modifications to parse them.

That said, the telemetry format could be improved and extended, and made 
simpler. aprs.fi already supports Kenneth's proposed telemetry format, but 
it still has a fairly limited number of telemetry channels.
