I wonder what happened to SDK/WDK releases for most recent Dev channel builds (Cobalt 213xx). It's exactly four months now without an SDK release if you look at the Flight Hub and I recall that SDK tools were supposed to flight alongside respective Windows releases. So far only Iron 203xx builds were made available from the Insider Preview SDK/WDK download page.
If you must keep multiple editions in the Dev channel, I would very much prefer the option to select from relevant editions of the Insider Preview SDK/WDK download, just like Windows 10 Insider Preview ISO download page lets you select an edition from all available channels.
