That PR (once merged) should allow users to have a global settings file, eliminating the need to copy anything between workspaces. With that said, this seems to come up every now and then ( redhat-developer/vscode-java#1356 ).

@testforstephen @fbricon we've briefly mentioned, re-evaluating which compiler options are worth ignoring by default. Might be worth putting together a list and ignoring them.

Agreed. It's definitely worth optimizing the compiler options for default values. I think users care about only a small fraction of the compiler options, and if we can optimize those options ahead of time, it can save them time.
