In the hopes of mitigating one form of dangling-markup-based exfiltration, Blink plans to block requests whose URLs contained both removable whitespace (`\n`, `\r`, `\t`) _and_ raw less-than (`<`) characters. https://github.com/whatwg/fetch/issues/546 lays out the strategy and justification in more detail, proposed patches to URL and Fetch are up for review at https://github.com/whatwg/url/pull/284 and https://github.com/whatwg/fetch/pull/519 respectively, and Blink's "Intent to Remove" might be helpful: https://groups.google.com/a/chromium.org/d/msg/blink-dev/KaA_YNOlTPk/VmmoV88xBgAJ.

CCing achristensen@ who's had helpful comments on the URL patch, though I don't think they're in favor of the exact implementation strategy outlined there. :)

WDYT?
