At the very least, Adobe should turn over the current registry state if

Even, might I ask where the compression tag is registered?

As there is apparently no one no longer in charge of the maintenance of the registry, I'd consider that the registration is: https://gitlab.com/libtiff/libtiff/blob/master/libtiff/tiff.h#L191
