I expect most platforms will continue to be the same, but I don't know
about Windows 32. I'd personally like to see Windows 32 support end,
but there may still be some interest. Mainstream support for Windows 7
ended a long time ago; extended support for Windows 7 ends at the
beginning of 2020. Microsoft just announced an extension for bulk
customers with deep pockets, so who knows. Are many of them likely to
be 32 bit?

AdoptOpenJDK can provide binaries for as long as they want to: it
doesn't affect the jdk8u project. June 2023 is right for JDK 8, but I
wouldn't be surprised if it goes on beyond that.

That sounds about right.

I don't know what AdoptOpenJDK would do with their builds, but I

If applicable, yes.

Let's talk about binaries. If you're using any kind of a Linux/GNU
system you'll want to use your distro's packages and update manager,
so we don't need to talk about Linux.
Binary downloads, are, therefore only really relevant to Windows and
(perhaps) Macintosh. I want the future updates project(s) to produce
official Windows binaries (perhaps built and tested jointly with
AdoptOpenJDK, but we haven't decided) and I'd like to see Macintosh
