Migrating to Hack simply isn't feasible for most users of MediaWiki. Most distros don't have packages for HHVM, and it's not straightforward to build AIUI.
Once you've figured that out, then you're going to quickly realize that you need a cron job to regularly restart HHVM because it'll OOM/crash/etc. So either you have downtime or multiple HHVM processes.
On the MediaWiki development side, we've been forced for fork all of the external libraries we depend upon to support Hack. This includes basic tooling like composer, phpunit, codesniffer, and so on.
There are probably more reasons that could be listed, but I think you get the idea of why Chad considers it to be a non-starter.
