As for the note E itself (xxx|xxo), then that's pretty much a disaster of a compromise on the majority of cors due to keywork and finger spacing as the low E tonehole (the one directly under RH3) is placed higher up the instrument than it should ideally be and made too small in diameter to bring it down to pitch, therefore resulting in a poor quality note.
The forked F vent ideally has to be arranged to remain open when E is played to help vent it and closed as soon as RH3 is held down, hence the floating rocker arrangement to the side of the RH main action. As already mentioned, using the RH Eb key will help further vent E but will sharpen it, whereas on pro medels the LH Eb key will further diminish the venting of E by closing down the split RH3 fingerplate (for the D#-E trill) while opening the Eb key.
A much simpler arrangement of the forked F vent is doable and often used on student model cors to keep the cost down (Howarth S20 through to S40C cors), although it will cause some tuning problems in the altissimo register where you'd use the low C key which should close off the forked F vent when it's held down - which is why pro level cors have the floating rocker arrangement which allows that. On these cors with this simpler F vent arrangement, the F vent remains open unless both RH fingers 2 and 3 are held down together.
The last new Rigoutat cors I've seen had a closed F vent (just like on oboes), although that was around 20 years ago since I last saw a brand new Rigoutat cor as they're not all that popular here as Loree and Howarth cors are the most popular and Marigaux cors are gathering more traction.
