Hi Jacek,
Thank you for raising this concern to Google Ads API team.
With regard to your concern, you may inquire with the
Product support team whether ad serving would be impacted if userlist changes as this is more of a product related concern. Regardless of which platform (API or UI) the changes are implemented, ad serving behavior should be better discussed by the Product support team.
Let us know if you have any questions.
Regards,
