NodeJS and unsupported old locales for plural rules?

[sven-oly]

NodeJS version 76 gives 436 failures in plural rules. Of these, 216 are reported for compact sample numbers, e.g., "1c6", which is the same as ICU4C and ICU4J.

However, the other 220 of them are for old locales including "in", "sh", "tl", "iw", "mo", etc. In each case, the results give the actual supported language tags as shown below for "in" (Indonesian) which has the modern tag "id".

{"test_type": "plural_rules", "locale":"in","label":"104","type":"cardinal","plural_type":"cardinal","sample":"0.0","hexhash":"3b059d08c3a377bacba90611a5fa967a7fcf5951"}
--->
{"test_type": "plural_rules", "unsupported_locale":"in","supported_locals":["id"],"test_options":{"type":"cardinal"}}

My question: should we use the actual supported locale when it is found?
