To detect a "locked file" as a safe change to reject and fail on, wouldn't
Subversion have to know quite a bit about the underlying filesystem? This
can be surprisiingly difficult, and is partly why lock files exist, to
abstract that subtle knowledge into a more tangible "no, we're not kidding,
leave this alone while we're doing atomic operations" stage. I'm not saying
it's infeasible, just potentially more comlicated than you may realize.
