My understanding is that they are suggestions. Like, if you want a story concept, here are some I'd enjoy. I think it's actually in the rules that you don't have to write one of their prompts, you just need to pay respect to their likes and avoid their dislikes like the plague.

And personally, as a giftee, I'd much rather receive a story my writer felt personally passionate about than something they forced themselves to write because I left it as a prompt.

If, on the other hand, you're able to fit in some aspects of their prompt/s, then bonus.
