I not have much knowledge of this, but after a quick look at the 
source code, I saw the ISO language code is used by the 
transliteration filter.

ISO language code is  also used by the Xapian search engine, I 
suppose we can't search Chinese or Hebrew or English texts the 
same way. See: https://xapian.org/docs/stemming.html

And if I recall correctly, ISO language code is used in Lucene 
searches by JSword.

Is there a benefit over the SIL database?

SIL International is the registration authority for ISO-639-3.

"SIL International (formerly known as the Summer Institute of 
Linguistics) is a Christian non-profit organization, whose main 
purpose is to study, develop and document languages, especially 
those that are lesser-known, in order to expand linguistic 
knowledge, promote literacy, translate the Christian Bible into 
local languages, and aid minority language development."
