The effect I would look at is oxidation and volatilization of low level, parts per million peach flavor compounds in the mead. To minimize this we run as low a primary temperature as convenient and run the primary under an air lock
My main concern would be say a year down the road, the honey and alcohol overpowering the peaches.
Clean alcohol does not have much flavor, Threshold is around 1%. Acetaldehyde (oxidized ethyl alcohol) is detected at lower levels, around 10 ppm. Again air exposure ,,, so top up or fill with marbles etc.
Yes Honey notes build with time, ,, but years, which is complimented by a natural oxidation of peach aroma. I don’t see any way to prevent age other than drink it in two years. ,,, Commercial folks fight oxidation with techniques as nitrogen flushing transfer pipes, nitrogen flushing the press, floating tank lids, and nitrogen flushing or vacuum corking when bottling.
Wine is a hedonic food, and
low levels of byproducts add complexity/ interest which makes it better.
