# Feature: #78415 - Global Fluid ViewHelper namespaces moved to TYPO3 configuration

See [forge#78415](https://forge.typo3.org/issues/78415)

## Description

By storing Fluid's namespaces in `$GLOBALS['TYPO3_CONF_VARS']['SYS']['fluid']['namespaces']` we can allow adding or
extending the global namespaces from third party packages in for example `ext_localconf.php` or by simply specifying
the namespace arrays in `LocalConfiguration.php`.

In terms of performance there is nearly zero impact but in terms of flexibility this should provide the ultimate way
to manage global namespaces as configuration; something that currently is only possible by implementing custom
ViewHelperResolvers.

## Impact

-   Site administrators and third party ViewHelper packages will be able to manipulate the global
    namespace `f:` in configuration
-   Third party ViewHelper packages will be able to register new global namespaces
-   Template developers can use such global namespaces without first importing them and can use them
    in all Fluid templates regardless of context.
