That's correct and expected for the MBR partitioning approach
(which is considered "mostly outdated" today).

Because you _cannot_ define more partitions than up to 'h'.
This is a hard-defined limit of MBR-style partitions (as
they are initialized with bsdlabel).

You cannot. You need to use the GPT partitioning approach
and repartition your disk. With gpart, you can create more
than 'h' partitions, but the partitions will have different
names, such as ad3s1p1, ad3s1p2, ..., ad3s1p10, ad3s1p11, ...
and so on.
