For me, it just took around 4 seconds to open the Files screen.
Remember that Files is a work in the earliest stages of development. It is, I think, a response to the fact that many Evernote users work wqith file attachments more than notes. The idea has been to develop something that will all the developers to see what is proving useful. So feedback is definitely going to have some influence. But if it really doesn't fly then I imagine Files could disappear as suddenly as it appeared.
If they are monitoring just @bmcl26 and my use then expect it to go soon
