Indeed. Unix philosophy is many tools that all do one small thing well. Cat handles opening a file and sending it to another file. I start pipelines with cat whenever possible, in case later on I have to drop in zcat or similar instead.

For example, preferring the cryptic `something | grep . >/dev/null && ...` over `something | grep '..*' | wc -l`.
