 I will understand that.

 At the same time I think that this function is an attractive feature of
 5.0.0.

 Using the wp_set_script_translations function in themes and plugins,
 the translation function can be used within JavaScript.

 Currently, '[domain]-[locale]-[handle].json' under the theme and plugin
 can be used.

 However, '[domain]-[locale]-[md5-hash].json' can not be used.

 I expect that this problem can be solved.
 And, I think "Host name comparison condition" is important.
