StringTemplate - why it is an unsealed interface?

[Patrik Duditš]

Hello,

I've been experimenting with StringTemplates recently for a few weeks. One
thing that appeared odd to me is that StringTemplate is defined as an
unsealed interface, as if it would make sense for users of the API to
create their own implementations of it.

I would like to ask whether that is an omission, or there is some other
underlying reason for that.
