What issue? If there was an actual issue with such a situation we'd be seeing posts about it. I've owned more decocker model pistols than I can remember and never had an issue arise from the decockers use. I've used the decocker on my PCR, 75BD,P-07 and 97BD PLENTY and they still function flawlessly. No indication of any wear problem. 14,000 rounds through the PCR, 22,000 rounds through the 75BD and 12,000 through the P-07.
The items that tend to wear on CZ pistols have been well documented here but sear wear from decocker use hasn't been one I've seen here or elsewhere so as is said in the link you posted it's an unfounded myth. That was 23 years ago and there are a whole lot more BD models in circulation today and this just has never come up.
