So?
As I say, its not as if I'm doing random edits or working with undefined
fields.  I'm not editing the RAW data, just the extant exif fields.

While I agree with you in the global sense that exif is poorly defined,
the changes I'm talking about are with well defined - as in previously
defined but absent fields.  Its not as if I'm screwing around with the
DPI or lens settings!  Yes there are a lot of ill-defined and/or
critical exif values.  I'm not talking about those, leave them along.
leave the DATA alone as well.

But under *some* circumstances someone who knows his camera well enough,
can address *very* *specific* use cases to alter *some* and *only *some*
exif fields.

This is not for the beginner!
I never claimed it was.
