Harfbuzz update to 5.1.0?

The latest version of Harfbuzz is 5.1.0.
The current one use by Lime is 1.8.8 ( GitHub - openfl/libharfbuzz ), which is very outdated .

Is it in OpenFL’s future plans to update the Harfbuzz library?
Is this task very difficult?

Part of this pull request, which I think we’re planning to merge in a bit, is updating Harfbuzz to a newer version:

That’s are great news!
All of the stuff in this update looks neat !
