1809: Is Windows To Go still broken?

In the initial wave of reports for things that were broken in the first release of 1809, there was included a fatal BSOD on attempting to boot Windows To Go:


It is related to WppRecorder.sys, affected both "official" and "unofficial" To Go installs, and was only apparent when the boot device was an external USB drive/enclosure supporting UASP. It was raised in some of the MS community threads at that time.

Three workarounds have been circulated which seem to work, at least for now:

• Delete WppRecorder.sys prior to boot, and replace with the corresponding file from 1803.
• Disable UASP globally by replacing uaspstor.sys with a renamed copy of usbstor.sys prior to boot.
• Disable UASP for the affected boot device via the registry of the ToGo install.

I have used the fist method and confirm that it works for me.
I have been checking the "fixes" in the re-release of 1809 and the subsequent patches, and do not see mention of this issue either specifically, or by reference to the offending drivers.
Is this on MS's radar?
