You might easily get the same prejudice from data flow diagrams - or
plumbing.
Personally I find that using cat makes things simpler and less error
prone when reusing pipelines in shell history.
For example it's easier to edit
cat file | foo
into
cat file | bar | foo
or cat file? | foo
than editing
foo < file
into
bar < file | foo
or cat file? | foo
