Great list, Oliver - absolutely agree about all of this.
For anyone thinking re: no.6 that xto7 is a complete answer to the whole OMF question, please note the issues I have had with my first attempts at using it for audio:

OMF is absolutely critical and it has to work impeccably every time under all circumstances, something that FCP legacy managed far better than AVID ironically. Third party solutions which may or may not work under all circumstances are worse than useless in a time-sensitive professional environment.
So my only quibble with your list would be moving OMF right up to the number one slot. And while we're at it, let's have OMF import as well which is the one thing that I still really like about Media Composer.
