There's no point in it really. That's why we have add ons board and formerly RTB which you can browse through Daprogs orbs thing
Except the Add-Ons board is a mess of add-ons, you can't specifically look for vehicles, weapons, etc, then there are dead links, creators that go inactive and never re-upload their add-on
And the add-ons on the various archives may be broken or have newer and/or more functional versions available elsewhere
