ESP32s2 Touch Sensor Application Question

I am in the middle of designing a hobby product that uses ESP32s2. The product is placed in an aluminium casing and I have a design-related question I would like to ask. I hope to learn something new based on the answers I find here.

I would like to implement the touch sensor functionality without making any changes to the current casing design (cutting holes for buttons and so on) - is connecting the whole casing to a touch pin instead of a ground pin (currently done) a stupid design decision?

Thank you for any advice
