de glazing cylinders

I suspect some broken rings in my track machine, and am tearing it down now.
I dont know if this is going to be a regular thing or not. Theoretically no - I am std boost and trying to manage fuel to 12.5AFR or lower. However I have had plenty of mishaps which have screwed things up from time to time. But if I incur this problem on say an annual basis, how many times can I afford to deglaze these cylinders without damaging the bore coating.
Is it strictly necessary to deglaze - will the rings bed in without it? I know it should be done, but is it possible to get away without it, in the interests of preserving the life of the cylinder?
