As I mentioned, my initial take on implementation was
using standard pipes instead of named pipes (not having read
or perhaps having glossed over the 'named pipes' aspect).
I think you're missing that process substitution is a word expansion
that is defined to expand to a filename. When it uses /dev/fd, it
uses pipes and exposes that pipe to the process as a filename in
/dev/fd. Named pipes are an alternative for systems that don't support
/dev/fd.

Try this:
echo <(cat /etc/passwd)
