Consider switching to LGPL licence #1
Description
https://www.gnu.org/licenses/why-not-lgpl.html
Using the ordinary GPL is not advantageous for every library. There are reasons that can make it better to use the Lesser GPL in certain cases. The most common case is when a free library's features are readily available for proprietary software through other libraries. In that case, the library cannot give free software any particular advantage, so it is better to use the Lesser GPL for that library.
This library is one of several that provides a modrinth api client, so it seems it would be better for it to be LGPL licenced. I am mid-development on a modpack management tool which is also GPL licenced, but I intend to provide a LGPL library for my tool's functionality as well. I would like to use this library, but I would be forced to licence all my code under the GPL or switch libraries as it stands now.
