@tferr On what are you basing the decision to declare something "Discontinued"? If you look at the pom.xml for this project, as well as the sidebar on the project's wiki page, you'll see it listed as "Minimal" support, with @larrylindsey in lead and reviewer roles. I understand that when people stop maintaining things, they often do so without notice. But I feel we should be pinging the current official team members of each plugin before unilaterally declaring it discontinued or obsolete. 😅

@ctrueden , I took a very quick and coarse look at the repos taking note of the last time their /src/main/ had changed. Fiji_Archipelago became noticed because the last changes to /src/main/ were 8 years ago. I now see that this approach is extremely simplistic. I actual forgot you have annotated everything nicely in the pom. 😞

It was not my intention to be draconian about this (or offend any project). @larrylindsey , @ctrueden : Apologies and do let me know if this should be closed (or modified)
