While true it is a good reminder that a ton of legacy devices are going to break after 2021-01-11.

It's not all-at-once but only beginning on 2021-01-11. Certs are valid for 90 days and the usual renewal period is 60 day.

So if you renew latest on 2021-01-10 your cert will be good until begin of April.

The server admin also has the choice to defer that to at least 2020-07-01, if they configure their ACME client to prefer the legacy chain.
2021 you mean?
Might not be so bad. Firefox uses its internal certificate store, and Chrome will have its own certificate store soon as well.
