Thanks for this!
I've only just loaded the latest ADMX files for Edge, and comparing against this guide:
Allow users to proceed from the SSL warning page - is actually Allow users to proceed from the HTTPS warning page in Group Policy.
Minimun SSL version - is actually Minimum TLS version in Group Policy.
[Aaron Margosis] The policy templates available now are newer than the ones we built the draft with. One of the improvements was to replace "SSL" references with correct terminology.
Configure Microsoft Defender SmartScreen for trusted downloads - this was missing from Group Policy completely.
[Aaron Margosis] Track the registry value (HKLM\Software\Policies\Microsoft\Edge!SmartScreenForTrustedDownloadsEnabled). The policy setting name is now "Force Microsoft Defender SmartScreen checks on downloads from trusted sources."
Other settings were fine!
