What is Cleanup Probability Settings For OAuth

Question

I am not getting the implementation of Cleanup Probability settings which you can find at Stores > Configuration > Services > OAuth > Cleanup Settings > Cleanup Probability.

From the Magento docs, it has below definition

Specifies the number of OAuth requests before cleanup is launched. Do not enter 0 to disable cleanup.

But if you check it's usage, you will see below code

Method: \Magento\Integration\Model\Oauth\Token::afterSave()

public function afterSave()
{
    parent::afterSave();

    // Cleanup old entries
    if ($this->_oauthData->$this->_oauthData->isCleanupProbability()()) {
        $this->_getResource()->deleteOldEntries($this->_oauthData->getCleanupExpirationPeriod());
    }
    return $this;
}

So whenever a token saves happens, then if the condition $this->_oauthData->isCleanupProbability() met, then it will remove then old token entries.

Now checkout the isCleanupProbability() method.

Method: \Magento\Integration\Helper\Oauth\Data::isCleanupProbability()

public function isCleanupProbability()
{
    // Safe get cleanup probability value from system configuration
    $configValue = (int)$this->_scopeConfig->getValue(self::XML_PATH_CLEANUP_PROBABILITY);
    return $configValue > 0 ? 1 == \Magento\Framework\Math\Random::getRandomNumber(1, $configValue) : false;
}

The default value of $configValue above is 100. That means the above method depends on 1 == \Magento\Framework\Math\Random::getRandomNumber(1, 100) expression. The chance of becoming this condition true is rare.

So basically, removing expired tokens based on a random condition does not make sense to me. I can update this setting to 1 which will always trigger the removal process. I feel this settings needs to be a select box with values "Yes", "No" and do the operation accordingly.

Or we dont need this checking here at all. This operation makes sense in a cron job and do not need to do in a token save operation.

If you see any other valid usage of this setting, then please share it here. Cheers!
