[Question] Preference not working in di.xml

Hi,

I have a custom module where I'd like to extend the Base Handler

<preference for="Magento\Framework\Logger\Handler\Base" type="Custom\Foo\Handler\DefaultHandler" />

Strangewise this does not work in this specifc case, while other preferences are working fine like

<preference for="Psr\Log\LoggerInterface" type="Custom\BarFoo\Handler\BaseLog" />

Thanks for clarification

Best
