Thanks to everyone who worked on getting this out!

For downstream consumers of the work done towards "Java 21 Support",
are there any best practices/requirements around announcing this when
some preview features are not yet complete ?

Alex pointed me to https://openjdk.org/jeps/12 (regarding preview
features) :

"The desire for feedback and the expectation of quality means that
these features are not "optional"; they must all be supported in full
by every implementation of Java SE $N."

That seems to imply we shouldn't declare it as "Java 21 Support". Has
this happened before or is this a non-issue? Would the marketplace
entry linked above be subject to this as well ?
