Why Xresolution,Yresolution,ResolutionUnit coudn't be changed?

In tag description tags marked as couldn't be changed after write. Why not?

As I understand this parameters don't take a part in libtiff calculations and do not influence to the file consistency. So why it's could not be changed to other values?

It is a real situation while a resolution coudn't be detected during creating the image. But it could be corrected by user for example.

Of course I made changes for myself in tag descriptions.

If there is no reason not to do this, it will be fine if this tag description will be changed in the next libtiff release.
