So I'm one of those people who plays e6 before f5 to play the Classical Dutch while avoiding the anti-Dutch lines, which works out quite well for me. The one group of anti-Dutch players who don't seem to get the hint are the Staunton Gambiteers. When they can't play 1. d4 f5 2. e4 against the Dutch, they seem happy to settle for 1. d4 e6 2. c4 f5 3. e4, without seeming to realize just how much the c4 e6 move pair helps black in fighting against this gambit.
The first time I saw this was an OTB tourney game against a higher rated opponent who I'd never beaten before, and it caught me off guard, so I didn't play it as well as I should have. I still got a good position out of the opening, but we ended up with a draw.
I just saw this variation again this past week, in a chess.com correspondence game. My opponent answered my 3. ... fxe4 with 4. Qh5+, and I got a rather silly miniature out of it. Somehow, with a time limit of 5 days per move, he overlooked a mate in one on the 11th move of the game.

I have to wonder how that guy got to 1800 on chess.com, even with the ratings on that (and most internet sites) being highly inflated compared to OTB ratings.
So I don't need any help playing against this gambit, but I'm curious about what it's called. This line is mentioned in Simon Williams'
Play the Classical Dutch, but no name is given for it. What does everyone think of calling it The Not-As-Good-As-The-Staunton Gambit, or The NAGATS Gambit for short?
