thanks

The only thing suitable for posting is "lmao". As the title says:
   $ comm   --total  --output-delimiter= <(echo a; echo b) <(echo a) | cat -A
   ^@^@a$
   b$
   101total$

Support for the NUL delimiter was explicitly added with:
https://github.com/coreutils/coreutils/commit/0e46753d7

You're correct that the support / docs are inconsistent,
especially with the subsequently added --total option.

I'll fix the docs and --total option upstream.

thanks,
