How to determine version of baked script extensions data?

[cmyr]

I'm trying to determine the version of the ScriptExtensions.txt file used to generate the baked in data in the icu_properties crate. The headers in the icu_properties_data crate state that they were generated from CLDR 45.0.0, but afaik script extensions are separate from CLDR. Is there any way for me to see what the source data was?

edit:

to make this perhaps a more actionable issue: is there currently any way for me to use the script & script extension data from unicode 16? I've tried rebuilding manually using icu4x-datagen and the data still looks out of date (specifically ScriptWithExtensions::new().get_script_extenstions_val('\u{2bc}') is returning the default script, but should be returning Beng Cyrl Deva Latn Lisu Thai Toto per the link above.)
