we will allow situations such as ``` a/b/1.txt a/b ``` and ``` a/b a/b/1.txt ``` we are going to document that this usecase is not supported and we will never support it, if any application does this users have to delete the top level parent to make sure namespace is accessible at lower level. rest of the situations where the prefixes get created across sets are supported as is.
