gptel Buffers List - PR or separate package?

[bhutley]

I opened a PR yesterday with some quick code I wrote that adds a gptel-list-buffers function giving a window with a list of gptel buffers, so you can easily delete old buffers, etc.

I'm wondering now whether this actually belongs in the gptel repo, or whether it would be better as a small separate package?

On one hand, I have found it generally useful.

On the other hand, it is a totally separate file that I could just make a separate package. This might be preferable for keeping the main gptel code-base small and tightly focused?
