Maybe I'm not understanding your point, but according to my tests chomp sill strips out "\r" when using binmode on Windows.

D:\test>od -c win32.txt
0000000   l   i   n   e       o   n   e  \r  \n   l   i   n   e       
+t
0000020   w   o  \r  \n
0000024

D:\test>od -c nix.txt
0000000   l   i   n   e       o   n   e  \r  \n   l   i   n   e       
+t
0000020   w   o  \r  \n
0000024

D:\test>perl -wpi.bak -e "BEGIN{binmode STDIN; binmode STDOUT;} chomp 
+$_;" win32.txt

D:\test>perl -wpi.bak -e "BEGIN{binmode STDIN; binmode STDOUT;} chomp 
+$_;" nix.txt

D:\test>od -c win32.txt
0000000   l   i   n   e       o   n   e   l   i   n   e       t   w   
+o
0000020

D:\test>od -c nix.txt
0000000   l   i   n   e       o   n   e   l   i   n   e       t   w   
+o
0000020
