Question Is there a risk to use DTD?

DTD general entities are defined on chapter 4, page 110.
Although, the article available at the link hereafter tells us that hackers could use DTD general entities to make a kind of DoS attack named 'XML bomb' (see § 'XML bombs' in the article): https://msdn.microsoft.com/en-us/magazine/ee335713.aspx
Do you think that despite of this risk, we can keep on using DTDs in our XML documents or, on the contrary, do you think we should now avoid using DTDs and update our parser settings so that it does not parse DTDs anymore, or update them with some restrictions (see § 'Defending against XML bombs')?
Thank you in advance for your answer.
Kind regards.
