Can you add some documentation for the new parameter? Since it doesn't even have a name here in the base class declaration, it's a bit mysterious as to what it might be for...

[lindsayad]

My very poor excuse for why I didn't do this initially is that I will have to comment out the parameter name to avoid unused warnings. Will a commented out parameter name still show up in the doxygen? Either way I can still articulate something in the doxygen wrt that parameter

[lindsayad]

relevant issue: doxygen/doxygen#6926

Looks good to me, I'll merge later today unless @roystgnr has any objections or gets to it first.

Test MOOSE mac failure definitely seems unrelated:
