The standard says that an ETag must be surrounded in double quotes:
https://tools.ietf.org/html/rfc7232#section-2.3
Although browsers tend to be lenient, omitting the quotes can confuse/break some kinds of proxies and other tools that demand compliant formatting. For example, Sandstorm.io enforces strict HTTP usage for security reasons and will block responses with invalid ETags.
