Since introduction of website_visitor, we don't need to identifiy the lead with a lead_id cookie. The visitor is identified and if a lead is created with the contact form, the lead is created and linked to the visitor. To avoid losing data, each time a visitor send a contact form, it creates a new lead. All those leads are linked between them via the website_visitor. As the website_visitor already has the lang set on itself, there is no reason to keep the lang_id of crm_lead at enterprise side. So that lang_id on crm.lead has been moved to community. This commit is directly linked to another one in enterprise See https://github.com/odoo/enterprise/pull/4834 to get more details. Task ID : 2028059 PR #34624
