Which MUAs exactly do ignore the "charset" of an email and try their own
guessing instead?
Or which MUAs exactly do not set a "charset" so that the receiving MUA
might have a reason for guessing?

With which MUA and which charset settings of the users?

People want their names written correctly in changelogs.
It is therefore on-topic if the result is something like "kernel
maintainers shouldn't be using Eudora" or "kernel maintainers using pine
should upgrade to Alpine" or something similar.
