With further testing, TEXINFO_XS=requiredifenabled does not
really work properly:

$ mv perl/XSTexinfo/Parsetexi.la{,-DELETE}
$ cd perl
$ TEXINFO_XS=requiredifenabled perl -w t/02coverage.t cartouche
ok 1
ERROR: document_parser_errors: no document_descriptor
ERROR: document_global_information: no document_descriptor
ERROR: document_global_information: no document_descriptor
...

and more error messages.

I would have expected an error message, like the following:

$ TEXINFO_XS=required perl -w t/02coverage.t cartouche
Parsetexi: couldn't find Libtool archive file
set the TEXINFO_XS environment variable to 'omit' to use the pure Perl modules
