I want an interface that supports efficient appending without requiring a
separate building phase or other hassles. Does this not exist?
I get that a library author might want to deal with the hassle of
alternatives. But as an application author there are times that all I care
about is a clean and simple interface that supports efficient appends.

Sequence is not used nearly enough.
Not really. Seq has high constant factors and for small sizes is often slower than plain lists. Nor is it space-efficient (for big sizes).
It probably has its use cases, but most of the time you'd be better off with one of the other choices:
* plain old lists * difference lists (trees) * lists "without remorse" * vectors * lazy vectors (lists of vectors)
