  Regular black holes are generically unstable because of the classical
phenomenon that goes by the name of "mass inflation" which destabilizes the
inner horizon. In a recent article, [Phys.Rev.D~107~(2023)~2,~024005], it is
argued that semiclassical effects due to Hawking radiation can cure this
instability, and some concerns are raised against the validity of previous
analyses showing its existence in the first place. In this short comment, we
explain our reservations regarding these recent claims, and reiterate the
relevance of the mass inflation instability for regular black holes of
astrophysical interest.
