Honestly, I like the flexibility of at least having a way for the user to add a custom style for new tab links. Whether the default style should be different may be a point of contention, but unless there is already another way to add a different style to new tab links, I think it would be beneficial to add one.

If you feel the default styles for new tabs don't match the PR, I'll remove them. The core goal of this PR is to provide the ability to specify different tab styles for different link types.
