Even when Mozilla does fully remove stuff from their root store, in some cases it has taken distros a year+ to ship the updated version
Not to mention stuff like this: https://bugs.launchpad.net/ubuntu/+source/ca-certificates/+b..., where Ubuntu just unilaterally reverted Mozilla’s removal of a cert in their package, because it was breaking nuget… Note that this was early 2021 — Mozilla removed Symantec from their trust store in October 2018!

In general it just seems like a bit of a mess.
