I think we are talking semantics here. The entries you list are clearly designed to SEPARATE STD activity from REAL flying so you cannot subscribe to the notion that STD time contributes for example to the PIC flying required for the upgrade of CPL to ATPL where PIC flight time means pilot in command of a real flight.
One good reason for that is that STD time is recorded as 'total session time' not 'flight time'. In some cases a two hour session in the box may have less than one hour of synthetic flight time so use of total session time to inflate genuine PIC time would not, I am sure, be acceptable.
