Static Content Deploy in developer mode without force flag is broken in 2.3-develop

[hostep]

Preconditions (*)

1. Magento 2.3-develop branch, I tested with commit 5860041
2. PHP 7.2.20

Steps to reproduce (*)

1. Setup 2.3-develop installation
2. Make sure it's in developer mode
3. Run bin/magento setup:static-content:deploy

Expected result (*)

1. Getting useful error:

$ bin/magento setup:static-content:deploy

In DeployStaticContentCommand.php line 108:

  NOTE: Manual static content deployment is not required in "default" and "developer" modes.
  In "default" and "developer" modes static contents are being deployed automatically on demand.
  If you still want to deploy in these modes, use -f option: 'bin/magento setup:static-content:deploy -f'


setup:static-content:deploy [-f|--force] [-s|--strategy [STRATEGY]] [-a|--area [AREA]] [--exclude-area [EXCLUDE-AREA]] [-t|--theme [THEME]] [--exclude-theme [EXCLUDE-THEME]] [-l|--language [LANGUAGE]] [--exclude-language [EXCLUDE-LANGUAGE]] [-j|--jobs [JOBS]] [--max-execution-time [MAX-EXECUTION-TIME]] [--symlink-locale] [--content-version CONTENT-VERSION] [--refresh-content-version-only] [--no-javascript] [--no-css] [--no-less] [--no-images] [--no-fonts] [--no-html] [--no-misc] [--no-html-minify] [--] [<languages>...]

Actual result (*)

1. Getting very obscure error:

#0 vendor/symfony/console/Command/Command.php(255): Magento\Setup\Console\Command\DeployStaticContentCommand->execute(Object(Symfony\Component\Console\Input\ArgvInput), Object(Symfony\Component\Console\Output\ConsoleOutput))

#3 lib/internal/Magento/Framework/Console/Cli.php(107): Symfony\Component\Console\Application->doRun(Object(Symfony\Component\Console\Input\ArgvInput), Object(Symfony\Component\Console\Output\ConsoleOutput))
#4 vendor/symfony/console/Application.php(145): Magento\Framework\Console\Cli->doRun(Object(Symfony\Component\Console\Input\ArgvInput), Object(Symfony\Component\Console\Output\ConsoleOutput))
#5 bin/magento(23): Symfony\Component\Console\Application->run()
#6 {main}

Further findings

After git bisecting, it revealed commit 9ffe7eb to have caused the problem, this is part of PR #24044

@PascalBrouwers: maybe you could have a look at what's going on here? Thanks! 🙂
Is not super important but might be confusing for newcomers in the Magento world.
