“Salient” seems to have lost its original meaning, and people mostly use it as if it were synonymous with “relevant” or “pertinent”. This is unfortunate. It's from Latin salīre, which is to jump, and it originally meant something that jumps out at you. In a document, the salient point isn't necessarily the one that is most important, most crucial, or most worth consideration; it's the one that jumps out.
It is useful to have a word specifically for something that jumps out, but people no longer understand it that way.
Cognates of salīre include “assail" and “assault”, “salmon” (the jumping fish), and the mysterious “somersault”.
