What about using a variable directly (without the @<(echo ...)? Does that still leak?

[โ€“] notabot@piefed.social 7 points 1 month ago

Yes, that will still leak as the value of the variable will be substituted into the command line before it's executed, so it'll show up in the process table. Using the <(echo ...) redirection is replaced by a file descriptor that connects to an anonymous pipe.
