I have two small suggestions; otherwise looks great.

Should this go in as log known issue, with the actual fixes in CLDR-19189 ?

otherwise this can't merge until data fixed

@macchiati thanks, but should this be a log known issue until the data is fixed? or leave this PR open awaiting data fix? It can't merge as is, since it fails.

I think it would be good to add as a logged known issue and then we can discuss in the next TC meeting how the TC prefers to resolve this in 49.

Logged known issue is fine for now, but we need to document this as a Known issue on the 48 release page, with pointer to the ticket/PR that fixes it, so that people can cherry pick.

logknownissue is as follows:

CLDR-19189 https://unicode-org.atlassian.net/browse/CLDR-19189

@macchiati nothing fails, so probably we can remove the logknownissue?

My mistake, these seem to be known issues still
