Apparently this is because of this tag, which would be an error if it weren't experimental:[...]So it's probably a bug in lintian, which was latent until very recently, because we hadn't tags with such property.If you mean experimental tags, we've had at least for a few years now.
What I meant is that none of them would have become lintian error if we had removed "Experimental: yes" flag.
