  In Phys. Rev. Lett. 128, 137001 (2022), Wang $\textit{et al}.$ address an
important problem in the overdoped cuprates, taking the first steps toward
understanding the structure of real defects in these materials, in this case
the apical oxygen vacancy, $\mathrm{V}_\mathrm{O}$, that sits immediately above
the planar Cu. However, the approach taken has some issues, which we outline in
this Comment.
