 Related: #47272, #48116.

 As noted in comment:36:ticket:55603:
 > There is precedent for blocking a site from upgrading when a PHP
 extension is missing. In WordPress 5.2, the
 [https://make.wordpress.org/core/2019/10/15/php-native-json-extension-now-
 required/ native JSON extension was marked as required] (see [46455]).
 When an upgrade was attempted and a site did not have this extension
 loaded, an error was shown and the update was cancelled.
 > ...
 > One other thing to note is that an error code specific to the scenario
 where the JSON extension missing is returned, which allows the number of
 sites to being blocked from an update to be tracked in .org's mission
 control to gauge whether this deprecation ends up being problematic or not
 (see [46560]).
