Asking for the users of FontSubstitutionDuringLoading (alt-N) shows one user. Asking for the methods with source containing "FontSubstitutionLoading" shows three methods.
One of the two "missing" users of FontSubstitutionLoading is StrikeFont class >> #familyName:size:, whose literals include an Alias mapping #FontSubstitutionLoading to a class named FontSubstitutionLoading.
Why doesn't this show up as a user of FontSubstitutionLoading?
(StrikeFont class >> #familyName:size:) literals at: 6 "=> #FontSubstitutionDuringLoading=>FontSubstitutionDuringLoading" Smalltalk bindingOf: #FontSubstitutionDuringLoading "=> #FontSubstitutionDuringLoading=>FontSubstitutionDuringLoading"
BUT. The former is an Alias, and the latter is a ClassBinding, therefore they are not #literalEqual:.
At first blush it seems sensible to say "users-of means accessing any binding that (eventually) resolves to the value of this binding here". This would pick up ClassBindings that pointed to Smalltalk globals at: #Foo, as well as Aliases to ClassBindings that pointed to that class.
What would be wrong with that approach?
