Insurance - is this collision now "on record"?

Hi.

Someone reversed into me whilst I was stationary. (Bizarre story really. They were engaging in a road rage incident with a pedestrian at the time.)

- My bumper is a bit scuffed. Their car is undamaged.
- They have taken full responsibility.
- They have reported the incident to their insurer, including my name and possibly registration plate.
- I am not planning to make any claim in relation to this, and neither are they.

From a pragmatic (rather than contractual) point of view, should I declare this incident to my insurer now, and for the next 5 years at renewal?

For clarity, if they hadn't already given the game away by reporting this, I wouldn't even be considering it.

Is this now on a database somewhere and will come back to bite if I don't declare it and then need to make an actual claim in the future?

Thanks.

Thanks for this, and thanks to all.
