Maximum Limit of Sites on Exclusion Lists in DSPs

When managing exclusion lists across various Demand-Side Platforms (DSPs), is there a universal cap on the number of domains these lists can contain? For example, Google’s DV360 explicitly states that line items are limited to a combined total of 10,000 URLs and apps (source: https://support.google.com/displayvideo/answer/6071450?hl=en). This limit appears consistent even when additional domains are included through a Channel, as only the specified maximum can be scanned before bid decisions are made. Are there any other resources or articles providing further evidence on this limitation across other DSPs?
