Why assume that everyone who touches Java code, uses an IDE to do so?
If you write code 90% of the time in a frontend or scripting or other kind of language where a lightweight code editor like VSCode is the peak of productivity — and then have to fix bugs in a Java codebase the other 10% of the time — then you're likely just going to work on the Java project using VSCode, rather than learning a whole extra (more complex!) tool just to increase your Java productivity.
Docland seems like it would be a good and helpful resource for the people who do things that way.
