is there any reason why this is not merged ? Is there any other plans for the future design of this package ?

I guess nobody had time yet. In any case, it is something that needs to be discussed anyway, as there was a reason why we added Requires - I can't exactly rembember why, although I was the one who did the changes.

It is also nothing urgent, as no bugs are fixed and no new features are added.

I fix it because there are a lot bugs, I just can not load graph6 module.
And keno find the similar bug. Well, I forgot to mention those bugs in the pr.

This should probably be done with extensions now

[filchristou]

yes, can we close this ?
