@gggeek's comment on constructor BC is also valid here if we want to backport this fix, alternative is that we do a v2018.09.0 release, then it's not a must.

Any opinions? @gggeek @crevillo

Indeed: +1 for adding BC constructor methods

+1 - additional BC constructor methods would be nice. So 2 constructor methods - something like this:

function ezfUpdateSearchIndexSolr( eZScript $script, eZCLI $cli, $executedScript ){ ... }
function __construct( eZScript $script, eZCLI $cli, $executedScript ){ ... }
