Following on from T226766: Avoid explicit commit references in composer.json in code meant for public consumption, T226156: Phan job fails on CI for mediawiki/core REL1_3, https://gerrit.wikimedia.org/r/#/c/integration/config/+/519793/ and the mediawiki-core-php72-phan-docker jobs
Phan in 1.31 and 1.32 won't run on mediawiki-core-php72-phan-docker because it has PHP 7.2, not 7.0.
As such, the phan jobs have been completely disabled in the branch, pending a longer term solution.
I don't believe we want to continue running jobs on PHP 7.0... So the options are to leave things disabled, or backporting whatever is necessary to run phan compatible with PHP 7.2 to 1.31 and 1.32
