Not for commercial twin turbine helis doing 160 kts,using it to carry extra load and less fuel.
I think that is the general idea of commercial aviation! Our lords and masters want more bang for their buck. If we all did an IFR approach every time SVFR is declared then I'm sure you and your colleagues would soon get fed up. We are all on the same side, just trying to get the job done safely and efficiently and often a two second explanation can do a lot to placate even the most impatient crews - "hold at XXXX due to blah".
As for declaring an emergency, you can see the P&J headline now can't you?
"North Sea Chopper in Fuel Scare Horror etc, etc."
We need to avoid this at all costs for obvious reasons. ATC do a great job at ABZ most of the time. Pilots at ABZ do a great job most of the time. Sometimes a little understanding on both sides goes a long way.
