I have changed this.
FWIW, I took my cue from the `--help` of ld.lld, assuming it would be a suitable authority.

Over coming changes we'll evolve to something more like that, but not exactly. The users of `-static` on PlayStation are a small, distinct group, internal to SIE. Over the last decade or so `-static` has - for better or worse - evolved into something very particular, here. Once all the functionality that should be in the PS driver is actually here, there's perhaps a chance that it can be rationalized.
