it really is no different now. while it's true that good jungle today is 4 parts genius to 1 part scenius, the fact is that there IS a scene--albeit tiny, and spread quite thin across the globe--in which real drum & bass music is made, played out, and enjoyed, with major-league "drum & bass" acting as an incredibly dense smokescreen to outsiders. you could also say that the producers and participants in this so-called "leftfield" scene (a misnomer, since it's entirely faithful to the original music) are no more aware of what's happening in the dnb mainstream than the disenfranchised former junglists are aware of them. they basically associate with each other. it's no hardcore scene, but it's not as if they each operate within a bubble, either, severed from any notion of community.
it simply has to grow, but it seems unlikely to garner much more interest if people are only seeking to replicate the identical sociocultural conditions of 1993. i'm personally grateful that internet forums, as disconnected from LDN as they are, have allowed the spare handful of stalwart junglists around the world to connect with and vibe off of each other, and throw parties, and form labels--there would be a lot less interesting music.
