We're at the stage where most things should work on php7 (some pages/revision only work with php7, even), so we would like to offer it as a beta feature for the adventurous user.
Technically, we just need to set/unset the cookie PHP_ENGINE to the value "php7".

This should probably go in Tech News, as the HHVM beta feature was too. It could repurpose from issue 39, 2014:
'''Recent software changes''' * You can test a new [[Special:Preferences#mw-prefsection-betafeatures|Beta Feature]] called PHP7. It should make editing faster. Please [[phab:|report bugs]] if you see them.
All it would need is a link to a message on the mailing list, like done for HHVM: https://lists.wikimedia.org/pipermail/wikitech-ambassadors/2014-September/000948.html
Very good point @Mainframe98 - in fact I was planning to write an email to wikitech-l once the beta feature is set up and I have the green light from everyone involved in the project before activating it.
Just one clarification - we're not moving to PHP 7.2 because it's faster, we're doing it as HHVM dropped support for PHP.
Please [[phab:|report bugs]] if you see them.
To notify Tech News, see Notice. Small nitpick: Please avoid linking to the generic Phab front page. :) [https://phabricator.wikimedia.org/maniphest/task/edit/form/1/?projects=projecttag1,projecttag2 foo] could be more helpful (full URL as ? breaks stuff when using [[internal|links]]).
@Krinkle did mention he saw a couple fatal errors that looked worrisome, so I'd wait for him to comment before backporting the beta feature and announcing it.
That's what the old entry did, except it linked directly to Bugzilla.
Is there any specific task/project Tech News should link to?
As indicated in https://www.mediawiki.org/wiki/Beta_Features/PHP7, you should use PHP 7.2 support probably
Is the end goal to switch support to php7 by default? If so, what is blocking that from being set as default at the moment?
Basically, what's still missing in T176370 and... testing! Which is what we're starting to do with a Beta Feature.
Change 484798 abandoned by Jforrester:
Add PHP7 beta feature
Reason:
We're just going to go with wmf.14 rather than back-port.
