This is not really a bug, please read the info message you have to confirm when unlinking a master document:
https://github.com/pimcore/pimcore/blob/a9f787995202fa4729ab26405c940464ae7f35f4/bundles/AdminBundle/Resources/public/js/pimcore/document/settings_abstract.js#L130

If I overwrite something, like an entire page, and than delete the content master document all changes I've made are lost. How can I handle this if a customer has this problem due to lack of knowledge to first delete the content master and then recreate the entire page?

Reading the info message and not just clicking "ok" probably helps 😉

But then it's too late, because everything is already customized :wink:

I can either click "yes" and loose all information or click "no" and nothing happens.
A more userfriendly way in my opinion:

• Keep all overwritten blocks, bricks etc
• Delete the content master document connection
