Given this "framework" is predominantly a collection of other people's (usually apache/mit) work, where is the BOM/licence text including all of the dependencies?
And why has the author attempted to licence their likely sub 100 lines of glue code under the GPL?
I don't see the point in using something like this which is basically a prefilled go.mod with some other files with a pretty stock organization.
I've used Pagoda (https://github.com/mikestefanello/pagoda) in the past which makes a show of displaying its nature as a wrapper around a bunch of community libraries, and is documented as such. They also make effort to document the interfaces for each component so you could easily replace them with your own implementations to avoid getting stuck due to the "framework". This is my preferred approach for all of these "starters" now since using pagoda.
