It is relevant and this is exactly what constitutes major difference
when you work on such a project. You don't need to think how to handle
various things that require data persistency even if temporal one.
Your /tmp and /var are writable from the very beginning as if you are
using HDD. This alone makes USB pen drive a lot different to place it
into another category.

Even if you decide to install some additional software, you don't need
to create the image from scratch, with USB pen drive you follow the usual
routine.
