splitting SDcard to multiple partitions fat/ext3/4 still necessary

I know from old Andoid OS threads that it was necessary to split format an SD-card in fat32 and ext3 or 4 partitions.

I now use ANdroid 4.4 and got myself a 128GB SDcard.

Simple question: is it still neccessary to reserve a ext3/4 partition for the OS ? Else I would all format to fat32
