It's fine for skyscrapers. The Empire State Bldg isn't going anywhere. It's dumb for thin flexible skyscrapers that will accumulate microfractures in a relatively short time span and whose steel structure is insufficient to support the building in the face of significant concrete degradation.
Microfractures =/= global strength loss. Additionally, the concrete itself tends to strengthen over time. I guess I just don't understand what failure mode you are worried about.
There are thousands of slender concrete structures that have been in service (thus far) without issue.
