 Finds C-style array types and recommend to use ``std::array<>`` /
 ``std::vector<>``. All types of C arrays are diagnosed.
 
+For parameters of incomplete C-style array type, it would be better to
+use ``std::span`` / ``gsl::span`` as replacement.
+
 However, fix-it are potentially dangerous in header files and are therefore not
 emitted right now.

Nit: is adding the single quotes needed for this patch? It introduces quite some review noise. It'd be preferable to apply this as a separate (NFC?) patch.
