If all fares originating in the UK go up, then competitively it's still
a level playing field for the airlines

Not quite. Airlines that rely heavily on UK hubs will lose out to those
that use non-UK hubs, as more passengers will choose to change in Paris
or Frankfurt instead of London.

Both trips start with a flight out of the UK.
