Why isn't attachTo: document.body the default?

[rivaldi8]

Attaching the component under test to the document solves some common problems like form submission and clicks on checkboxes (see warning at the end). In fact, if you search for 'attachTo' in the project issues, there are lot of people that have problems because of it not being set. So, I wonder why it isn't the default if it makes test easier to write and more reliable. I guess there might be some drawbacks that made the project default to leave it not set, but I haven't found any explanation in the documentation. I was thinking of setting it globally in my project, but before I'd like to know of the possible consequences. Could someone shed some light on this?

Something similar happens with enableAutoUnmount, which causes some tests to fail if the component isn't unmounted after each test.
