Changing default namespace from operators

Hi there

Having a question about operator. Lets say I want to install ES Operator that will install on elastic-system NS. Is it there a reason why I should not change the default NS? Asking because I want to change it to something else

If is ok to change it … what whould be the best solution

Question is not related with Elastcsearch … is about installing an operator based on URL with predefined namespaces. I want a way to overwrite that namespace from the file w/o downloading the file and change namespace there and then run apply/create command

Is it there a quicker solution? Is it there a reason why NOT to do so?
