With respect to chronology and cause/effect, I'd point out that provision took effect in January 2022, so it's been of-concern for a while.
It was put into law in 2017 with the Republican TCJA, but section 174 was time-delayed, part of a general trick of having all of the tax-cuts and spending immediately, with any budget "balancing" items deferred as long as possible.
