This text was written long before Aware Systems worked to develop BigTIFF support for libtiff.

It shouldn't be surprising that people aren't jumping in to test when the definition of BigTIFF is still in flux, and has shown no sign of approaching a stable specification.

Given your title, I see that you should be justified in being apprehensive. There were quite a few people involved with developing the BigTIFF draft specification, including people from Adobe. There have been no changes since that time. There are at least two implementations. BigTIFF is a small natural progression from TIFF. It seems unlikely that an organization with some apparent position of authority (i.e. a standards organization or Adobe) will produce a document on their own. Perhaps an IETF RFC is the best avenue since the IETF has already published several TIFF-related RFCs.
