Hmm, I once transited in Heathrow in a return flight from europe to the US and had to go through Heathrow security for whatever reason, where they subjected me to liquids rules way stricter than either my source or destination did.
E.g. 1 day use contact lenses and prescription creams all having to fit in a tiny plastic bag. So I'm happy for this change.

The US mandates that you have to go through TSA approved security before getting on a flight to the US.
Either the security at your European airport wasn't good enough, or the transit at Heathrow allowed you to access to things that invalidated the previous security screening and so it had to be done again.
The bonus is that if you get to go through US Immigration at the departure airport then you can often land at domestic terminals in the US and the arrivals experience is far less tortuous. I flew to the US with a transit in Ireland a few times and it was so much nicer using the dead time before the Ireland -> US flight to clear immigration rather than spending anything from 15 minutes to 4 hours in a queue at the arrival airport in the US (all depending on which other flights arrived just before yours).
