For giving any functionality added, you can add the stock picking type (only incoming ones), and incoterm information to purchase order types, and pass this information when changing the order type.

If you don't want to call super as this is an isolate operation, you can do:

    @api.onchange('partner_id', 'company_id')
    def onchange_partner_id_purchase_order_type(self):
        if self.partner_id.purchase_type:
            self.order_type = self.partner_id.purchase_type.id

Although you don't do this change, change the if part to the new API possibilities (no need to check the existence of each field before accessing the subfields).

Order alphabetically

What about the last point?:

For giving any functionality added, you can add the stock picking type (only incoming ones), and incoterm information to purchase order types, and pass this information when changing the order type.

This should be both also conditional. If the value is set, then you overwrite whatever it has. If not, you leave the previous value.

You can add also instructions for the 2 new fields, but not blocking. 9.0 commits to be squashed on merge.
