I vehemently disagree. The relevant file name restrictions nowadays are those of Windows (no characters " * / : < > ? \ , file names don't end in '.', file names avoid special names such as "aux", "nul", "prt"). We have been leaving the 8+3 restrictions of Windows 3.1 (which disappeared from the marked around 1995-1997) between 2000 and 2011. Before that, it was commonplace that packages targeting DOS platforms had a special script for renaming the source files (e.g. [1]). VMS is a very small niche system. If such a renaming of source files was possible for DOS, it must equally be possible for VMS. Other GNU packages that use the '+' character in file names, independently of gnulib: gcc, glibc, binutils, coreutils, bison, gettext, clisp, gperf. POSIX is partially outdated, as has already been noted on this list.
