Err, no. It simply means that the particular symbol for it is bound only within the scope of the 'macrolet form. In practice, most of the time, the desire for first-class macros is really just the desire to bind a particular symbol to a macro within just a particular scope, and 'macrolet does that.
For other cases where a macro expansion should be used more often than just a particular scope, then usually the module or whatever is placed within a package and a package-level macro is used.
