For the sake of clarity, do you argue that upgrading a module using Odoo Shell is not a valid use case to be supported, despite the opposite evidence?

# use read() to not read other fields: this must work while modifying
# the schema of models res.users or res.partner
values = user.read(list(name_to_key), load=False)[0]

Recall that this works perfectly with Odoo 12.0. This is a step back. The comments on this feature indicate that the author is trying to avoid the exact problem I'm describing, and it works fine in 12.0, but not in 13.0
