It seems AERI is abandoned and causes some troubles for end users. like
Looking at the aggr file, it has not been touched since almost 4 years  .
i've tried to download an EPP package ( JEE ) and aeri cannot start. I believe no other project use it inside EPP.
is it the case ?
Maybe is it time to remove it from EPP?
Update sites are still present, so end users who want to use a newer version still can.
