Note: This will need a small patch in method
Pim\Bundle\ImportExportBundle\Twig\NormalizeConfigurationExtension::normalizeValueFilter()
In many cases (or almost always) the deployment processes do not use the developers local vendors content and/or use the composer.lock file to install the correct dependencies. This results into that any changes made in the vendors folder will get overwritten by composer.
I'd recommend to add your own NormalizeConfigurationExtension class and just to override the services class parameter pim_import_export.twig.normalize_configuration_extension.class to point to it. This way the changes won't get lost.
