Maximum number of exceptions in DLP policy

[leo85]

We have a very large tenant with thousands of teams, which can potentially all host a Dataverse for Teams environment. All these environments need to be governed, among other things by a respective DLP policy. We will likely have one policy for all Dataverse for Teams environments.

Is there a limit to the number of included/excluded environments for a single DLP policy?

Could there be a performance impact, for example on the time needed to open a Power App, if a DLP policy contains thousands of inclusions?
