Well, I wouldn't say that the existence or lack of labels would indicate the liveness of the mod scene, given that it already existed a decade before the concept of netlabels became widely known. But if you need an example of a netlabel that still exclusively releases modules, there's
Datamask or
Remute. There are still dozens of people on tracking scene IRC channels every day, it's far from being dead. All archives - including ModArchive, modules.pl and ModLand - have modules from way back until this very day and are still being updated, so they are far from being "archives of past modules".
