Running `steep check` based on a file created by `steep init` gives WARN.

[kuredev]

Running steep check based on a file created by steep init gives WARN below.

WARN -- rbs: set has been moved to core library, so it is always loaded. Remove explicit loading set

The SteepFile created by steep init has the following lines.

#   library "pathname", "set"       # Standard libraries

If I remove this comment out here and run steep check, the above WARN will be displayed.
I think "set" should be omitted from the SteepFile created by steep init. 🤔

Steps to reproduce

steep init
vim Steepfile # comment out `library "pathname", "set"`
steep check
