TypeError: unsupported operand type(s) for |: 'AnyChange' and 'Q'

[adk-swisstopo]

I am trying to compose a pgtrigger.AnyChange with a pgtrigger.Q like this:

class MyTrigger(pgtrigger.Trigger):
  # ...

MyTrigger(
  # ...
  condition=(
    pgtrigger.AnyChange('some_field') |
    ~pgtrigger.Q(old__geometry__poly__equals=pgtrigger.F('new__geometry')))

This fails like this:

TypeError: unsupported operand type(s) for |: 'AnyChange' and 'Q'

I tried to understand what makes the two types incompatible but could not figure it out. Is there a way to build a condition with a combination of AnyChange and Q? If not, would that make sense as a feature request? If yes, any guidance on how to go about it would be welcome.
