It's a reasonable assumption to make, though I'm almost positive there have been exceptions in the past (possibly all bugs, though).

What non-physical on-hit effects it blocks is handled on a case-by-case basis, though, which is why it's standard to have its interaction mentioned when describing damaging on-hit effects.
