I was more thinking about people defining methods on operation.

less -p 'defmethod.* operation)' $(grep -il 'defmethod.* operation)'
Reveals 9 files beside copies of ASDF that define methods on operation.
Some of them may or may not be affected in practice by making
operation not the root of the hierarchy.
POIU also does it, though if you change the base class incompatibly, I
can update POIU.

ITA's QRes also defines methods on operation (as you can see in the
parts that were open sourced); maybe other proprietary systems do,
too. Once again, if anyone is extending ASDF in proprietary system (or
just ones not on quicklisp), he'd be well-advised to be on this
