Nomenclature for Vaculitides

I finally got around to reading the 2012 International Chapel Hill Consensus Conference recommendations on the Nomenclature for Vasculitides:

Large vessel vasculitis (LVV)
* Takayasu arteritis (TAK)
* Giant cell arteritis (GCA)
Medium vessel vasculitis (MVV)
* Polyarteritis nodosa (PAN)
* Kawasaki disease (KD)
Small vessel vasculitis (SVV)
* Antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV)
* Microscopic polyangiitis (MPA)
* Granulomatosis with polyangiitis (Wegener’s) (GPA)
* Eosinophilic granulomatosis with polyangiitis (Churg-Strauss)
* (EGPA)
* Immune complex SVV
* Anti–glomerular basement membrane (anti-GBM) disease
* Cryoglobulinemic vasculitis (CV)
* IgA vasculitis (Henoch-Schönlein) (IgAV)
* Hypocomplementemic urticarial vasculitis (HUV) (anti-C1q vasculitis)
Variable vessel vasculitis (VVV)
* Behçet’s disease (BD)
* Cogan’s syndrome (CS)
Single-organ vasculitis (SOV)
* Cutaneous leukocytoclastic angiitis
* Cutaneous arteritis
* Primary central nervous system vasculitis
* Isolated aortitis
* Others
Vasculitis associated with systemic disease
* Lupus vasculitis
* Rheumatoid vasculitis
* Sarcoid vasculitis
* Others
Vasculitis associated with probable etiology
* Hepatitis C virus–associated cryoglobulinemic vasculitis
* Hepatitis B virus–associated vasculitis
* Syphilis-associated aortitis
* Drug-associated immune complex vasculitis
* Drug-associated ANCA-associated vasculitis
* Cancer-associated vasculitis
* Others

I'm not happy with the continuing trend of removing eponymous names. It's not because I particularly like the names, but in my opinion the new names are no more descriptive, are harder to say and spell, will be more confusing for patients and for non-rheumatologists (Every time I've said "granulomatosis with polyangiitis" to another specialist, they've look at me like I was having a stroke.), and will likely change when we know more about the pathology and etiology in the next 5-10 years. Also, if you're going to change a few names, why then leave the rest such as Cogan's, Behçet’s, Takayasu's and Kawasaki's?

The only change I'm going to adopt is IgA vasculitis, simply because I constantly fumble over "Henoch-Schönlein".
