No you don't. You're spouting clueless FUDster bullshit as always.

And it only took you a few decades to do so...

No. Not all "Unix side" command-line tools in macOS are unaware of forks.
Some are; and some aren't.

I honestly don't care enough to recall or research it again. Do your own
research.

Try:

ls -l somefile/..namedfork/rsrc
ls -l somefile/..namedfork/data

How can you have used macOS this long without knowing this?

Aliases are based on inodes rather than hard coded paths and are therefore
far more flexible and powerful than soft links, since you can move or
rename the source entity without breaking the alias. You can also move the
Ali's itself without breaking anything. Aliases also work across file
systems and across networks to shared file systems.
