[TYPO3-dev] Deprecation strategy for BE viewhelpers

[Frans Saris]

Hi,

are the BE viewhelpers provided by the different core extensions part of
the public api?

I ask this
because TYPO3\CMS\Extensionmanager\ViewHelpers\Be\ContainerViewHelper is
deleted in master (https://review.typo3.org/#/c/22063/).
ext:media uses this one and now breaks in TYPO3 6.2.

Shouldn't the viewhelper be deprecated and not deleted so extension
developed for 6.1 still work in 6.2?

gr. Frans
