Should the Active Directory UDF support fine grained password policies?

[water]

Should the AD UDF support the fine grained password policy available since Windows Server 2012?

What do fine-grained password policies do?
You can use fine-grained password policies to specify multiple password policies in a single domain and apply different restrictions for password and account lockout policies to different sets of users in a domain.

From a support perspective I can say that of the 50 or so networks I encountered over the last 12 months only a handful were using this. That being said, I believe (like all UDF additions) it comes down to the level of effort for you to add it. If it is something you can add without tearing your hair out I think it has value; even if it will only serve 10% of users.
