Could someone please provide an update on reducing compartment overhead? Are we at a point where things like services/healthreport/HealthReport.jsm should be considered a "necessary evil" rather than a "gross hack?"
What other solutions besides concatenating files and lazy loading are there? Neither sound particularly appealing to me. I'd really like to be able to "pin" specific JSMs to shared compartments. Kind of a hybrid between CPG and the monolithic compartment that came before. I filed a bug on that a year ago.
