In the current situation only the entire tag is private. This limits its
usefulness since if you use a completely proprietary tag no other software will
do anything useful with it.

The proposal though is to allow amending of supported tags with private
add-ons. This creates an expectation that the tag will be generally supported
and carry around the add-on with it. I suspect it will be used not only by
private agreement for interchange with others, but as note-to-self in some
applications. (e.g. Turn on this feature or that.)

So it may be more generally used and therefore be a more significant issue. And
yet I am unclear as to the demand or need for this.
