Important: #80266 - Moved config.sys_language_softExclude to compatibility7

See forge#80266


The TypoScript option config.sys_language_softExclude to set certain TCA table fields to l10n_mode=exclude during frontend request runtime has been moved to compatibility7.

If any installation depends on this option in the TYPO3 frontend, the extension should be installed.

However, as the TCA option l10n_mode=exclude has been superseded by the TCA option allowLanguageSynchronization the actual use-case for this TypoScript setting should be re-evaluated.
