> I agree that, inherently, cache line size has nothing to do with topology. But on the other hand, it's particularly useful for parallel shared-memory applications (to avoid false-sharing),

The false-sharing part is where it makes as much sense as the cache
size, I believe, since it's related to the fact that there are several
processors in the machine. I'd thus tend to agree to include the
cacheline size.
