Advertencias de desaprobación de niebla al iniciar el servidor Rails

Migré mi aplicación Rails a Rails 6.0.1 y cada vez que inicio el servidor recibo estas advertencias de desaprobación de niebla. ¿Cómo puedo deshacerme de ellos? Curiosamente tengo una versión clonada de esta aplicación, que no da estas advertencias ...

Según tengo entendido, estás usando toda la fogbiblioteca. ¿Hay alguna razón específica por la que eres la biblioteca completa, por ejemplo fog-aws? En mi opinión, el uso de la fogbiblioteca completa tiene muy pocos beneficios, a menos que tenga algún tipo de aplicación / biblioteca de nivel superior que interactúe con todos los proveedores que fogofrece. Por lo tanto, sugiero que solo requiera la biblioteca / bibliotecas que necesita y deje el resto. Esto podría eliminar las advertencias de desaprobación.
