TYPO3 Core

I like to have new TCA setting(s) in select and group fields for

1) Automatic cache invalidation of related tables or
2) Running Datahandler Hooks (Trigger re-indexing of relations, etc.)

This should be realized in core to make extension development easier.

Maybe 2) is enough

'tags' => [
    'label' => 'select_single_12 foreign_table selicon_field',
    'config' => [
        'type' => 'select',
        'renderType' => 'selectSingle',
        'foreign_table' => 'xy_tags',
        'runHandlers' => 1                          <-- Run Handlers for "modified relations" 
        'flushCache' => 1                            <-- Flush cache for "modified relations" 
   ],
],

Modified relations can be received from \TYPO3\CMS\Core\DataHandling\DataHandler::$mmHistoryRecords

What do you think about it?
