I just don't know whether anyone cares -- or, worse, if it's not permitted under the laws of some jurisdictions.
The only grilling I've gotten has been from USCBP at LHR when I checked in for my outbound to the US on a US passport and for my return to the UK on an Aussie passport (I had to because of Visa placement). They thoroughly inspected both passports and questioned me for a bit. No biggie. Otherwise, no issues. No questions from US immi about the fact that I have nearly no stamps in my US passport and the ones I have are only US stamps, and no questions from anybody else.
