Please make flower and spawn block of warden lower

Hello Mojang, I just wanted to ask you for a suggestion regarding flowers in minecraft, the flowers can be picked up by hand so that means that when the earth breaks, for example the fact of having a hundred flowers that break and end up on the ground can cause a drop in fps, it would be practical if the flowers could only be picked up using shears because this will avoid lags and would be linked to the fact that you are using shears to obtain a block of foliage. And also this isn’t a change that would make the game better but when i was mining and my fresh world I woke up the warden who scared me very much (I'm 19) and who killed me in two ultrasonic necks super cheat I was wondering if you can reduce the genration percentage of the block which wakes up the warden outside of the cite because I looked as a spectator and there was no city nearby so this was all i got a say beside that i love the game and the last uptade we are getting :)
