  We contend that the arguments provided in Phys. Rev. Lett. 130, 016001
(2023), purporting to show the absence of off-diagonal long-range order in hcp
$^4$He dislocation cores are misleading and incorrect. In particular, the
one-body density matrix averaged over the whole crystalline sample provides no
useful information on the possible superfluid behavior inside the
quasi-one-dimensional core of a dislocation in the crystal.
