The problem is that keys used today are weak - and the ones used in the past even weaker.
In 2030 it will be trivial for a nation state to forge an email sent in 2020 that matches today's DKIM, and for a bedroom hacker to do it for an email sent in 2010.
Encryption that we tend to use is good enough for now - but not for 20 years time. In the 2032 election when Donald Jr is dukeing it out with Ocasio-Cortez, it will be easy for Russia, China, Nigeria, or probably even 4chan, to fake some SKIM signed emails from 2016 showing they actually planned to secretly take over the country in a Kang vs Kodos way.
