You should read what I said.It really isn't difficult to edit that timer with proper tools and development practices.
And stop talking about the GCD it has no application to the topic at hand. You are continually confusing people with that false information.
As what I said was neither is going to get changed.
Gcd is relevant as GCD is the short timer that occurs after you plant.
Then there is an additional item usage timer on the crop which stops you from replanting again.
Of which neither the GCD or the item usage cooldown for crops will be modified. For which Sparkle has said would be very time consuming and we feel does not grant enough of a benefit to warrant the time it would take to modify and then test the planting time for every crop in the game.
