Didn't feedback from a recent survey find that passengers wanted more staff in customer facing roles to offer information/assistance etc? Can't remember where I saw it but it has been mentioned in the "Greater West" promotions. Considering IEP is going to be DOO compatible - It feels like FGW are going in the wrong direction.
Recently, a 5 car train pulled into a station near to me (usually a bit of a squeeze) but one of the doors wasn't on the platform properly, and as a result this door wasn't used thanks to the guard. - If this was DOO, someone could've easily stepped down not realising and broken their ankle or something. Doesn't bear thinking about really. I'd say a guard should be essential to the majority of services.
FGW's announcement the other week said specifically that 100 extra customer-facing staff would be taken on, though it did not specify exactly what they would be doing.
In cases such as the one you mention, where the train is a tight fit on a platform, then the trains will be programmed, as a matter of course, to only open doors that they can be 100 per cent sure will be on the platform.
Something like a third of UK passenger services are currently operated as DOO but I haven't noticed a catastrophic decline in safety standards over the past couple of decades since it became commonplace. Maybe the drivers are quite good at operating safely too?
And there is a small minority of guards out there who are quite happy to sit in the back cab and just work the doors, rather than venture out to be seen by passengers or check tickets, no matter what their employer's official policies say, so probably no bad thing if they can't use door operation as an excuse for their behaviour any more.

Wouldn't that mean lots of CCTV equipment to enable the driver to check it was safe to close the doors?
The cameras were part of the IEP specification. See page 20 of the document. Details of the various modes of door operation that will be available are on page 44
