IntelliJ Eclipse integration - should *.eml files go in version control?

There's very little information about these files, so I've defaulted to including them in my version control system, on the off chance they're critical.

This issue seems to support that assumption: https://youtrack.jetbrains.com/issue/IDEA-133542

However, I'm seeing these files produce a tremendous amount of churn - say, updating every commit or every other commit (several times a day) - even when dependencies don't seem to be changing all that much.

Do I NEED these files if I'm storing other IntelliJ/Eclipse project files?
