Do they still maintain it as in, it gets bug fixes and security patches? Technically yes, bug fixes and security patches are still produced for Windows Server. I wouldn't call it a good level of effort but it exists. They are happy to take your money for such a mediocre level of effort though.
Is it Microsoft happy path? No. Microsoft STRONGLY recommends that if you are running .Net (Core), you run under Kestrel on Linux in a container. Performance under Linux is much better than Windows.

Kestrel is more performant under Windows than Linux, but the container support isn't there
This is incorrect, all benchmarks including those from Microsoft have proven 10%-30% performance increase under Linux.

Here is Microsoft official ones, Linux beats out Windows in almost every metric.
