If you would have clang-format override the committer and retrospectively
apply subsystem style rules (rather than the rules used by a majority of
subsystems or those preferred by Linus for example) it would add friction
to code re-use, movement, comparison, any tree-wide program
transformation, and also subsystem boundary changes.

Per-subsystem style rules are inherently contentious and therefore good
candidates for the "leave alone" functionality discussed in the issue
tracker.
