New indexation protocol from Bing and Yandex

Yesterday Bing announced in the webmaster's blog a new protocol for indexation requests called IndexNow, that can be found with the standard URL structure /indexnow (can't put the link here, but just add /indexnow after the normal Url). With this new protocol you can submit a request of indexing for up to 10000 URLs for a single request, and Is also supported by Yandex. Even if Google didn't join in that, maybe they will be doing something similar because indexnow Is going to be a new standard (or at least that's how Microsoft and Yandex want to do), so they may feel the need to catch up. That would also be something useful from Google after the hyper-messy Title update that changed titols and stuff without giving any value, that would be a nice change for once.
