I guess it depends. Do you get a diagnostics if you instantiate the
templates? If yes, it is not a bug, the implementation is allowed but not
required to diagnose bugs in uninstantiated templates (the C++ wording
is if a template is invalid for all possible instantiations, then the
program is ill-formed, no diagnostic required or so).
It can be a QoI, but not everything can be diagnosed on uninstantiated
templates.
I'd suggest in any case to instantiate the templates unless you want to
check solely for the QoI diagnostics on uninstantiated templates.
