It's not something new, but possibly just a compromise.
It's apparent that we have no problem. We agree that the minister should appear. We don't just want to embarrass her and present her with a motion that would imply she's not responding to our request. If we could have a preamble, something to the effect of “Notwithstanding the fact that there are two weeks left”—or a week left—“we duly request that the minister still make it possible to meet with this committee.”
I think something along those lines....
