I see your point, however on balance given that a lot of people don't do any flying at all and just apply with current licences, (as do most of my friends) surely the fact they you fly regularly and are at least involved with something aviation related is worth more? I'm just playing devils advocate here btw.
The fact that you fly regularly could definitely help. At the same time a valid IR is a must for most of the airlines.
If you ask: at that worth it concerning my bank account, will I ever find an airline job? That's a whole different story.
There is some hiring right now, I don't think it will last for ever. That's all I can understand.
You could also try to focus on your current job and make a career in the GA.
If your immediate goal is the airline, I would definitely reniew my IR right now (finance permitting...).
