I wouldn't be so sure about this. There are plenty of brits in the US too, I'm not convinced that the majority of British GE applications actually happened from the UK.
I won't dispute it's still useful - but I don't see how it would affect the CBP workload: it seems more efficient to have them in the US rather than temporarily hire/station officers in the UK. After all most other nationalities also have to interview in the US (although there do seem to be interview locations in singapore at the embassy, and possibly in Dubai - but Dubai having preclearance means that CBP officers are stationed there long-term).
