> One of my favorite EU (or German? not sure)

Maybe there is also an EU regulation now, but at least in Germany the "Telemediengesetz" was introduced in 2007, where §5 "Allgemeine Informationspflichten" is responsible for the need of an Impressum.

That doesn't include a customer support email though. Most of the times, if not all at bigger companies, there's only an email address in the imprint for legal communication, but specifically not for customer support.

Legal communication importantly covers a subscriber cancelling their contract! This is actually one of my most common use cases for writing to the "imprint" email address.
