This isn't just force of habit. RFC 5646, Section 4.1 says clearly, "A
subtag SHOULD only be used when it adds useful distinguishing
information to the tag."
In many cases, perhaps even most, a tag that says "Huallaga Huánuco
Quechua, written in the Latin script" might not add useful
distinguishing information beyond one that says simply "Huallaga Huánuco
Quechua." A search engine (in the general data-processing sense, not
just in the Google/Bing/Yahoo! sense) already knows what characters are
used in a given piece of text; it doesn't need to be told.
The value of S-S lies in the ability to match tag or range A, which has
a script subtag, with tag or range B, which doesn't.
