give a counter-example, `Module` has `addUses` as well.
But if I want to call `addUses` on behalf of a module I've
defined, there is no corresponding
`ModuleLayer.Controller` method so I do have to define the
extra class, and that's a bit silly. This is an example of
an easy enhancement that would not affect the integrity of
the platform, would not significantly increase maintenance
burden (since the logic would be nearly identical to its
sibling methods), and would be easy to achieve.</div>

Module::addUses is for cases where code may need to create a SL that
loads a service that wasn't known to this module at compile time.<br>
<br>
ML.Controller is the equivalent of the --add-exports, --add-opens,
--add-reads command line options for the boot layer. There was
little motive to work through the implications of --add-uses and
--add-provides and the ML.Controller equivalents at the time. The
exception is the agent case where instrumentation may augment the
services used (or provided).<br>
<br>
Time has passed and I can only think of one request for --add-uses
has come up. That request didn't go very far because service binding
augments the module graph during resolution. A CLI option (or
ML.Controller equivalent) can only work reflectively, which is
post-resolution. This is of course too late for what the group
requesting this wanted. It hasn't been re-examined since then at
least not to my knowledge.<br>
