My 2022 Volkswagen e-Up has zero thermal management of the battery, it's completely passively cooled with no heating. Not that it really matters, people have tested it and charging speed only starts to degrade after 3-4 rapid charges in one day, with "rapid" in quotes(in tops out at 40kW).
I believe the eGolf which was sold in the US shares the same drivetrain and battery.

Different drivetrain and battery for the eGolf, but both of these are effectively 2013 EVs.

Almost all non-Tesla EVs offer a heat pump option. Most non-Tesla EVs sold do not have one. Just go to your local VW dealer or whatever and see what the specs are on the ID.4's on the lot is.

You can easily read about your example VW MEB platform battery configurations, including built in thermal management system, online at the Munro teardown, for example.
Perhaps you are changing the topic from your original thermal management to heat pump systems specifically?
That’s false since at latest 2013 in the US.
The past 12 years of BMW as a counterexample all have thermal management. Tesla too.
You may be remembering the original Nissan Leaf?
