# See https://docs.aws.amazon.com/apigateway/api-reference/resource/stage/#methodSettings
# for the paths needed to update these values. Note that the paths for these values have
# the form /a~1b~1c/GET (slashes in the resource path replaced by ~1, and GET is any HTTP
# verb).
#
# We can't remove individual values, we can only replace them with default values if they
# aren't specified. However, if a path/method exists in current_stage but not in props, then
# all the settings should be removed using a path like /a~1b~1c/GET.
#
# The wildcards may need some special handling.
