Note I would rather rename #morphicOpenWith: to #openAsTool or similar because (1) to not confuse with the rather old pattern "morphicOpen..." and "mvcOpen..." and (2) it already is in the scope of Morphic. No need to encode this in the selector, too.

Well, since Tobias started this refactoring in April 2017 to clear-up MorphicToolBuilder >> #open, this seems a logical next step to also have a #buildWith: in Morph.

Just my two cents. :)

#buildWith: is a method for just ToolBuilders. The clarity of the
decision of whether to build or not was articulated by the code of the
class responsible for it. A dispatch seems unnecessary here. In
fact, introducing Morph>>#buildWith: adds yet another muddle-method to
its already-large API, and now inherited by the entire hierarchy.
Will it invite people to start overriding it in subclasses as an
alternative way to use ToolBuilder? Maybe. I think they'll at least
be confused about why it's in Morph.

IMO, this is one of those times when a type check was the simplest and
best way to go.
