Mowing more frequently was better for the bees: *"Mowing frequency altered the evenness of bees within suburban yards, though the patterns we observed did not fully support our hypothesis, in that lawns mowed every week and every three-weeks had higher evenness (Fig. 4d) and richness (Rarefaction curves; Fig. 2) when compared with the two-week treatment."

You also ignored the important part where the study pretty explicitly says there are better practices including wilding they just aren't likely to gain acceptance with tedious home owners.

A New England study on lawn care attitudes and behaviors found that householders were concerned about water quality and thus were willing to try al- ternative lawn care approaches that were more environmentally friendly (e.g., higher mowing height, reduced fertilizer application). However, the authors also noted significant barriers to changing be- haviors including concerns that the alternative lawn care would not be as aesthetically pleasing, would incur additional financial burdens, and would require more time for upkeep (Eisenhauer et al., 2016).
