Anybody knows why Nomenclature of subclades of Haplogroup K have still various different letters designating them rather than simply just starting with K?
Like for instance the simplest designation (current ISOGG designation in parentheses) would be:

K(K)
....K1 (LT)
.......K1a (L)
.......K1b (T)
....K2 (K(xLT))
.......K2a (K1)
.......K2b (K2)
.......K2c (K3)
.......K2d (K4)
.......K2e (M)
.......K2f (NO)
.......K2g (P)
.......K2h (S)

this would make Haplogroup R, K2g2, thus offsetting every nomenclature downstream of R by 3 letters/numbers. Similarly Haplogroup O would be K2f2, again offsetting anything downstream of O by only 3 letters/numbers.
I think this lettering would be more reflective of the phylogenetic reality of macro Haplogroup K than the current nomenclature adopted by ISOGG.
I understand that it would overhaul names used and are still being used in published literature, but then again the YDNA tree structure has undergone considerable internal structure change since the beginning of our current millennium.
