+1 from me, lending my voice to the crowd!
Effectively in many CRM setups I work with, “Contact Owner” translates to “Sales Contact Owner”. New ownership properties are created for different teams.
I’d create a workflow to clear the owner if the the team is not a sales team, but you can’t use Hubspot team as a re-enrolment criteria (to do this repeatedly if needed). So this option to not assign contact owner in the first place is important
