I wouldn't have thought airlines would consider commitment (or lack of) from looking at your IR status.
If I were about to pay lots of money to put a low-hour pilot on a difficult flying training course, and I can choose between someone who hasn't flown for a year(example) and someone who has, who would I pick?
That said, if you got to interview and your CV didn't mention your IR status then a lapse on financial grounds ought to be considered reasonable, if questioned.
I suppose I dunno really. G'luck!
