A fragment has continuous memory and allows to prepend and append respecting
its initial capacity.
A frame can be non-continuous.

I'm talking of what I have found as real needs in concrete projects. The
simple buffer functionality you are presenting don't satisfies my needs.
This doesn't mind that the abstraction don't have other uses, but instead of
appending what I use to need is to prepend headers.
