Appeal to ISO 639 RA in support of Elfdalian

Am I right in thinking that if swe was made a macrolanguage encompassing 
Swedish and Elfdalian, then the ISO 639 RA would have to register a new 
three letter code for Swedish proper, in the same way that a new three 
letter code lvs was registered for Latvian?  Let’s say for the sake of 
argument that this new code was svn.

The two-letter ISO 639-1 code sv would then presumably be equated with 
swe (just as it is at present) rather than with svn.  Just as:
lv is equated with macrolanguage lav rather than standard Latvian lvs,
ms is equated with macrolanguage msa rather than standard Malay zsm,
az is equated with macrolanguage aze rather than dominant Northern Azeri azj,
and so on: https://en.wikipedia.org/wiki/ISO_639_macrolanguage

The correct code for Swedish (proper) on the Internet would then become 
svn rather than sv, in the same way that the correct code for standard 
Latvian is lvs rather than lv.  Except that Google (e.g. in Google 
Translate) takes the pragmatic approach of continuing to use lv for 
standard Latvian, ms for standard Malay, etc.

This seems to me like a messy situation which would be best avoided 
except when there is no alternative.
