Agreed, but it is the importers responsibility to ensure that it is
either supplied with the correct regional power cord, or supply one
themselves.

Many US vendors get it right, but just as many don't seem to care, or
even know that things are different outside of CONUS.

Adapters supplied with "new" products are AFIK not permitted, though it
often happens.   The problem there, is the quality and safety of such
adapters is often poor.   (Often low cost brittle plastic things from
the Far East.)

In this case, as the PSU is intended to be used with a device that has
exposed metallic parts connected to one side of the DC lead, I suspect
(I admit that I do not know for sure) that the AC input to that PSU
should include a safety ground, connected to (among other things) the
transformer inter-winding shield.

It's been a very long time since we've seen any similar PSU's for
laptops and similar devices, that do not have a three pole power inlet,
that includes a safety ground.  Even, if the DC output is fully isolated
from anything on the AC input side.

Take care.
