The owner wants to seal the balcony, and the property company requires the owner to sign a letter of commitment. Should the owner sign it?

Hello, lawyer, I am the owner of Lishui Jinyang Community in Zhangshi Development Zone, Shenyang. Our community just delivered the house in the first quarter, and the balcony of the house is semi-closed. Some owners who are as anxious to decorate as I am need to close the balcony, but the property requires all owners who need to close the balcony in the community to sign a letter of commitment, the contents are as follows: Letter of commitment to close the balcony by themselves. I am the owner of unit _ _ _ _ _ _ _. After being informed by Lishui Jinyang Project Department of Wanlian Hengde Property Management Co., Ltd. that there are potential safety hazards in self-closing the balcony, it still insists on self-closing the balcony. And voluntarily promised the following: 1. If the balcony part closed by itself falls off for any reason, I will bear all the consequences; 2. From the moment I closed the balcony myself, I was responsible for the maintenance of the balcony's thermal insulation and waterproof function. Will not claim the relevant rights from the original maintenance unit. 3. I will bear all the losses caused by the closed balcony to the adjacent owners. All losses caused thereby shall be borne by myself; 4. I promise to undertake the above three commitments independently, and bear possible related civil and criminal responsibilities. Commitment: _ _ _ _ _ _ Dear lawyer, please help us to see if the owner should sign this commitment letter. Waiting for good news, thank you!
