We have checks in place to verify that the reference_id column on oc_comments exists, e.g.:

spreed/lib/BackgroundJob/CheckReferenceIdColumn.php

Lines 51 to 57 in ada7048

	if ($schema->hasTable('comments')) {
	$table = $schema->getTable('comments');
	if ($table->hasColumn('reference_id')) {
	$this->serverConfig->setAppValue('spreed', 'has_reference_id', 'yes');
	$this->jobList->remove(self::class);
	}
	}

spreed/lib/Capabilities.php

Lines 250 to 252 in ada7048

	if ($this->serverConfig->getAppValue('spreed', 'has_reference_id', 'no') === 'yes') {
	$capabilities['features'][] = 'chat-reference-id';
	}

Since Nextcloud 29 the reference_id column was added to a migration, making it mandatory for all installations:

https://github.com/nextcloud/server/blob/ae4a6e8d4454b7896d0e40f367096a26d999dbf0/core/Migrations/Version29000Date20231213104850.php#L49-L55

Therefore I suggest that we remove the BackgroundJob and the checks.
