These settings are indeed important for these functions, but I can't get=20
around the fact that it makes these APIs really cluttered and=20
complicated =E2=80=94 something that many functions in the grapheme_ / intl=
=20
extension already suffer from.

Is this API really the best way?

It seems that I came to a similar conclusion, but locales are much more=20
complicated than just languageCode_regionCode (for example, see=20
https://github.com/derickr/php-text/blob/main/tests/text-contains.phpt#L25)

You also don't really need a strength argument, as you can 'encode' that=20
in the locale name, like: 'nb_NO-u-ks-primary' (I know, it's rather ugly=20
and the list of options is vast:=20
https://www.unicode.org/reports/tr35/tr35-collation.html#Common_Settings
