Only big problem I ran in was with adding CORS, but that has been "fixed" in RC2 by allowing developers to edit the umbraco pipeline in startup.cs. Though that really need to be documented because currently you need to check the PR to see what the minimal required middleware and order is. Also, I believe there are alternative ways to add middleware in between other middleware by using a filter in a composer, that could use some documentation as well
