Thank you for pointing this out.

The change in question was made in service of tracking down residual 
users of a deprecated protocol during debugging, and was (obviously) 
not made with reference to any non-Squeak usage.

A reasonable fix is indeed simply to revert the method, as suggested; 
this remedy will will appear in a forthcoming update soon unless 
objections are heard.

Sorry for the hassle, and cheers,

   -- Scott
