I always thought the "frill" on the Vagabond looked silly. The Rifter is iconic; the Vagabond was recognizable but never struck me as an iconic hull of the Minmatar line.
I sympathize with those that feel differently and hope they accomplish their goal to make CCP "bring back the Frill", but I won't miss it.
FULL DISCLOSURE: I only started flying Minmatar combat ships in the past year compared to ~5 years of Caldari and Gallente.
PS - I'm back from vacation, more on the Kadavr Crimson Guard later.
