It seems unlikely that we will receive any official information 
before the forthcoming libtiff release.  There has been no sharing of 
recently assigned numbers on this list so that probably won't happen.

The harm which occurs due to conflicting with an existing proprietary 
assignment is likely very low.

Give the above, I am in favor of using the existing self-assignments 
for this next release, and forever after that.
