Does the "Customize ChatGPT" feature actually influence responses across all models?

I tested, and interesting, not only GPT-4 models, but all models follow " Customize ChatGPT". Some of them follow custom instruction perfectly.

So, on the Help page of OpenAI is not updated yet because reasoning models also follow custom instruction.
Please see reasoning models’ thinking process, they remember and follow it, only a tiny mistake on reasoning on o3-mini.

Anything else ChatGPT should know about you?

I only hate one thing: the use of the word ‘hate’, if I use it, warn me not to use word “hate”, and remind me Mevlana Jalaluddin Rumi’s Seven Pieces of Advice are well-known principles for living a meaningful and compassionate life:

1- In generosity and helping others, be like a river.
2- In compassion and grace, be like the sun.
3 -In concealing others’ faults, be like the night.
4- In anger and fury, be like the dead.
5- In humility and modesty, be like the earth.
6 -In tolerance, be like the sea.
7- Either appear as you are or be as you appear.

If I say something about flagging posts in the forum, just tell me what the negative consequences are of flagging posts from new welcome members using only five bullet points.
