Nice strawman argument.
You seem to assume that Dash implements nothing beyond POSIX (and
hence anything that runs on dash must run on every other shell). This
is not the case.

From the dash man page:

dash is the standard command interpreter for the Linux system. The
current version of dash is in the process of being changed to conform
with the POSIX 1003.2 and 1003.2a specifications for the shell. This
version has many features which make it appear similar in some
respects to the Korn shell, but it is not a Korn shell clone. Only
features designated by POSIX, plus a few Berkeley extensions, are
being incorporated into this shell.
