This has historical (or as I like to call it hysterical) reasons - on
Apache httpd anyways:

up until 2.2 FileETag used to default to All: http://httpd.apache.org/docs/2.2/mod/core.html#fileetag

All includes: Size, MTime, and Inode. INode is pretty much guaranteed
to NOT be the same accross nodes.

starting httpd 2.3.14, we made sure this is no longer the
case: http://httpd.apache.org/docs/2.4/mod/core.html#fileetag

The default is now Size and MTime


So long,
