That's good to hear!

I am not intimate with the HIERARCH extension, but I don't think that
there is any difference between a header that has the extension but
doesn't happen to have any HIERARCH keywords in it, and one that
doesn't have the extension.  If that's the case, and a user adds a
HIERARCH keyword to a non-HIERARCH header, you can assume they know
what they are doing and enable it without some funky switch (it won't
happen by accident).  If it's not the case, clearly you don't want to
write HIERARCH-enabled headers for all files.
