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

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 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?
