And all the more reason not to employ a perhaps undocumented perhaps
completely proprietary field.

We have "annotation/documentation" and "annotation/appinfo" ... isn't former
for documentation? If appinfo were defined as being explicitly for, or
limited to, documentation, then I would not be raising this issue.

Certainly we can all think of perfectly useful things that we can use
appinfo for. The problem isn't what good things it can be used for, rather
what bad things it can be used for.
