Comment (by jorbin):

 While this shouldn't be a problem for the vast majority of sites, not
 having JSON compiled into PHP will cause things to break in wonderful
 ways. See #18015

 I think a check in the core upgrader for json functions and a rollback if
 they are not available could be a warranted addition.
