Hello, 
I just read up the documentation on Odoo 14 Security in the fields section it reads: 
restricted fields are automatically removed from requested views.
Why does it throw an Access control error, when I add the field "vat" of res.partner to group" to  "sales_team.group_sale_salesman" for example.
class ResPartner(models.Model):    
    _inherit = "res.partner"    
    vat = fields.Char(groups="sales_team.group_sale_salesman")

Document type: Contact (res.partner)
Operation: read
User: 9
Fields:
- vat (allowed for groups 'Sales / User: Own Documents Only')
Shouldn't the field be automatically removed? 
Also it seems, that the acl error still persists, even after xpathing the groups attribute to the field in "base.view_partner_form"
