In any case, its unreasonable to expect us to never *extend* (not

Agreed.
However as I sit here and think about it, it may be worth adding a new
field *as early as possible* (read closes to the start of line) in the
field list that indicates a version, which can be used to determine the
fields and their position there in. This would make it very easy for
people to write strict parsers down the road. A simple three character
hex field (4 bytes including the leading space) would allow for 4k of
strict layouts. (Even more 0-9 and a-z or additionally A-Z.) Just a
thought.
