And then, beyond the theoretical "let's ignore implementation concerns" design issues, the fact is that this is another design like the `em` versus 'font-size' design. In implementations, this means they have to specially handle 'font-size' before most other properties, so they can compute `em` lengths properly everywhere else. This is useful and fine, but it's complex, and browsers try to limit the number of additional properties they have to process similarly.  Any of these properties would also be in this category, so browsers would be loathe to add them without a very good use-case backing them.
