Allow me to draw people's attention to the PREVIEW link in the banner of 
the generated javadoc. It shows all the preview APIs in the release on 
one page. This is very helpful for understanding the surface area of a 
preview feature.

For example, with Sealed Classes being the only preview feature likely 
to target JDK 16, the PREVIEW page shows that the feature's API is 
solely about reflection. It's clear that Sealed Classes do not 
introduce, say, a java.lang.Sealed class analogous to the 
java.lang.Record class introduced by Records in JDK 14/15 (and which 
would have appeared on the PREVIEW page had it existed then).
