Since Hebrew does not need any special line breaking rules, I doubt
using \XeTeXlinebreaklocale will have any practical impact here.

The language part of language.def is about TeX's \language, so it is
strictly concerned about hyphenation patterns and nothing else, so it is
the wrong place for the kind of modification you want.

Ironically, you seem to think \uselanguage does things like Babel's
language switching (switch hyphenation patterns, fonts, font encodings,
typographic conventions and what not), but it doesn't, it is simply a
way to switch hyphenation patterns using human readable names, instead
of relying on TeX's \language number which depends on what patterns were
dumped in the format.
