No, "rtl::Reference<VclStatusListener<Button>> mpStatusListener;" is fine

...as a member of ImplCommandButtonData (vcl/source/control/button.cxx), no need
to falsly warn "OutputDevice subclass 'rtl::Reference<VclStatusListener<Button>>'
declared as a pointer member, should be wrapped in VclPtr [loplugin:vclwidgets]"

Probably loplugin:vclwidgets should enable shouldVisitTemplateInstantiations()
and not try to second-guess whether an OutputDevice can be a template argument.
