Can someone confirm that all options(emoji ...) https://github.com/unicode-org/cldr/blob/latest/common/bcp47/collation.xml#L13-L31 are compatible with ECMA402? Except "standard" and "search" as the spec describe
13:03
<Richard Gibson>
that may depend upon what you mean by "compatible". The whole list and even made-up values are accepted by https://tc39.es/ecma402/#sec-initializecollator , but are not guaranteed to make it through ResolveLocale on any given implementation

Thanks Richard Gibson , I was looking at https://tc39.es/ecma402/#sec-intl-collator-internal-slots

<Romulo Cintra>
but was unsure if only those two must not be used or there is any other

<Richard Gibson>
no, those two are singled out because the Collator constructor uses a usage property
