It looks like the only time immediate mode is used explicitly (i.e., other due to `DeferredLintHandler`'s default state) is when resolving imports ([here](https://github.com/openjdk/jdk/blob/89e5e7ab73472b7d02aac5b8b0c7e9f26db6ec32/src/jdk.compiler/share/classes/com/sun/tools/javac/comp/TypeEnter.java#L368)). In that case, of course, there can be no enclosing `@SuppressWarnings` so that makes sense.

Can we use a similar "flush" strategy ? E.g. make the warnings be part of an import declaration, and then process them as part of a flush?
