Server 2019 - BPA STILL reports SMB1 should be enabled, and broken links

This is an oldy but still valid. I ran BPA against a management server, all machines are Server 2019 in our environment. It's now 2020, and BPA STILL reports:

The SMB 1.0 file sharing protocol should be enabled

We all know opening SMB1 is equivalent to uploading all your data to Facebook or the like. It's 100% unsafe. Why on earth is this a recommendation? The last OS that relied on SMB1 only (xp) is retired for years now.

Then there's the broken links in the BPA results. For example:

CachedOpenLimit should have the recommended value
http://go.microsoft.com/fwlink/?LinkId=246902

The link doesn't exist, same with several other recommendations. But I took this CachedOpenLimit example, as I can't even find proper documentation on the registry value at all. The FileServer tuning guide at https://learn.microsoft.com/en-us/windows-server/administration/performance-tuning/role/file-server/ doesn't even mention the CachedOpenLimit at all.

Why does this all have to be so cumbersome? And as we didn't changed the CachedOpenLimit ourselved, and value 5 seems to be optimal, why isn't that set by default?
