[plt-scheme] Is it important to understand continuations conceptually; not in terms of their implementation?

I get the feeling that it is important to understand continuations
conceptually, and specifically not in terms of their implementation.

The TSPL book, for example, does so; and I often see it quoted word
for word in explanations of continuations.

However, the number of articles that describe continuations in terms
of the stack far outweigh explaining them conceptually.

Does describing them in terms of their implementation serve as a
disservice? Will it be an impediment later on?
