says:
"If you have an eSIM, you can choose to erase your eSIM or keep it. If you erase your eSIM, you need to contact your carrier to reactivate your cellular plan."
which implies to me that whether or not the eSIM is retained is something you choose.
The bigger question to me is one of how you plan on clearing memory. If you use iCloud extensively the memory space might just fill up again.
