Did you remove Latg and Latf from the scripts standard? Which is exactly on-point to my message--it is useful to distinguish scripts in many cases that Unicode may not.
Latg and Latf are variants of the Latin script, distinguished in ISO 15924 for the reasons stated in ISO 15924. Those reasons are specific, and are not in the least bit analogous to the question of the identity of Phoenician and Hebrew scripts.
