i think left hand F is really necessary for D (or Eb) -F-E-F-D (or Eb) when played quickly. many other times it's optional. for example, if you look at the first rapid continuous sixteenth note passage in the 3rd movement of the S.Saens, you might be tempted to use LH F, but I prefer forked.
Here are a few other interesting examples:
1. Bach cantata 12: end of first measure going into second has G-F-F-Eb-Db. I don't like the sound of forked F on the quarter note second F slurring into a 32nd because it just hangs there, but it's a bit of checkmate situation, you're forced to go there!
2. Mendelssohn Scottish Symphony: oboe has low C-F-G, which is much easier to do forked, but one is tempted to reach for tricky LH F. Quoting John Ferrillo from his invaluable "Orchestral Excerpts for Oboe": "The forked F is a cleaner fingering on the downbeat, but the left hand F is more in tune and stronger."
I don't know about the in tune part, but stronger, I definitely agree. I'd say it's a rare oboe for which that is not the case (Loree Royal's maybe excepted, and I guess I'd need to try a more recently made C).
My conclusion: you need LH F for some fast work, but most fast work lets you get away with forked F, and LH F should be favored if possible when it's suspended or a climax note (like the Tsaichovsky 4 referred to by Max, where you want to preserve the timbre of the preceding Fs) except for instances such as the opening of the S.Saens where weak forked F has tonal advantages.
