The best is to not have to introduce a separate harfbuzz3 package, as
it really complicates things.

There are not that many packages that have a dependency on harfbuzz:

package/efl/efl.mk:ifeq ($(BR2_PACKAGE_HARFBUZZ),y)
package/libass/Config.in:       select BR2_PACKAGE_HARFBUZZ
package/mupdf/Config.in:        select BR2_PACKAGE_HARFBUZZ
package/pango/Config.in:        select BR2_PACKAGE_HARFBUZZ
package/qt5/qt5base/Config.in:config BR2_PACKAGE_QT5BASE_HARFBUZZ
package/qt5/qt5base/Config.in:  select BR2_PACKAGE_HARFBUZZ if \
package/qt5/qt5base/qt5base.mk:ifeq ($(BR2_PACKAGE_QT5BASE_HARFBUZZ),y)
package/supertuxkart/Config.in: select BR2_PACKAGE_HARFBUZZ
package/vlc/vlc.mk:ifeq ($(BR2_PACKAGE_HARFBUZZ),y)
package/webkitgtk/Config.in:    select BR2_PACKAGE_HARFBUZZ
package/wpewebkit/Config.in:    select BR2_PACKAGE_HARFBUZZ

So I would suggest to create a configuration that builds all those
packages successfully prior to the harfbuzz bump, and then retry this
configuration with the harfbuzz bump applied. This will give you a
sense of how much breakage the API changes are causing.

Best regards,

Thomas
