How to use mounted point

Hello, 

I building a new SQL Server 2014. 

We use mounted point to simplify folders administration. 

I'll would like to know if the following remarks still true: "Warning: SQL Server does not support use of mount volume / mount point root directories for SQL Server databases."

From this Link : https://support.microsoft.com/en-us/kb/819546

For now, we work around this problem by settings access rights directly on the disk and not on the root folder. 
Could we use this solution or have to create a folder and put all subfolders and files in it ?

Thanks in advance.
