Actually, if you wade through the 200+ pages of mindless unsupported drivel they spewed, you would see that they specifically mentioned regulating flavorings. They're also "seeking input" on what parts/components of the ecig device/hardware to control/regulate & eventually ban. They specifically mentioned things like lighters and cig cases as not being regulate-able, but they're reserving the right to regulate other (undefined) components... and asking for the public's "help" in deciding what those components should include.
I agree that it's not as draconian as I personally expected it to be - certainly those who currently use e-cigs have plenty of time to take care of themselves, what concerns me is those who haven't discovered (good) e-cigs losing the opportunity to beat the weed in the future.
Once deemed as a tobacco product, anything is possible. Enough press on children and flavors and we'll get tthe flavor ban. The right pressure from BT and a few well placed news reports of nicotine poisonings and the FDA can regulate nic in sealed cartridges only.
This is getting their foot in the door and declaring themselves gatekeeper. Be happy of the window currently opened but don't be too self assured about the future.
