Topband: Am I the only one in step?

That could be one reading, Don.

The other is that WRC Agenda time is intensely sought after, for many changes to spectrum allocations.

IARU was confronted with the prospect of failing on both its bids for WRC19 Agenda items and in effect prioritised the other (global allocation at 50 MHz) above the  Region 1 1.8MHz issue. Parts of the world (again particularly Region 1) don't have anything at 50 MHz and that seemed to offer the best prospect of gain for the most. So AI 1.1 at WRC 19 addresses that issue, and 1.8MHz extension/relaxation fell by the wayside. Again the 50MHz case results from spectrum clearance after band 1 broadcasting has dwindled to nearly zero.
