Thanks @jonathan-gibbons for your comments! I've tried to update the code based on them, mostly in https://github.com/lahodaj/jdk/commit/743f516c660b577035cdda4510a0bb97937fd9b2 and https://github.com/lahodaj/jdk/commit/e4b02827998fc2e8f19f983aabfb3d720b03d111

A big chunk of the update is generalization of the deprecated and preview list builders and writers into a "summary" list builder and writer. These should also now handle records. For record components, those are a little tricky, as (AFAIK) can't currently have deprecation/preview-ness for them (and hence there is no good way to test any support for record components in these). But the summary build and writer are looking for record components and will fail in case a record component is sent into them.
