I have no objections to this, and happily support this endeavour.

However, I currently track 8 packages via shell scripts (available via
nvchecker's "cmd" source), all found here[0].

Some of them require specific dependencies to be installed, e.g.
html-xml-utils for normalising/extracting HTML elements. Would we be
able to list specific dependencies in the .nvchecker files?
