On github it's configurable whether you allow it, maybe even on
per-branch basis. It might be the same on SF.

Git has integrity checking built in. Modifying commit message changes
commit shasum and people who synced end up with incompatible copies.

Modifying commit message is equally bad for git as changing files and
equally bad as stealth updates of released tarballs (package manager
fetches gcc sources and performs some checksums, but then upstream
decides to change the tarball in some minor way without changing its
filename, checksums are no longer valid and packages no longer work).

For SVN it's easier because everything lives on the server, there are
no integrity checks and commit numbers don't change.

I've been suggesting that for ages :)
