Not better.  Circumlocution does not help.  The MAY version here is exactly what you should write in this case.

(Of course, for more specific values of “handle that situation”, the MUST version may be appropriate.
But unsubstantiated judgement calls such as “is likely to” don’t belong into the spec.)
