Hi, I just released versions with Sf6 compatibility. I will hopefully and likely more time for this bundle since the project that uses it is receiving more attention.
I am also fine with adding maintainers to this bundle.

Hi guys! We've just found this issue while working on maintenance within our forks :) I'm working as EM in Answear, if you'd need some help feel free to shoot me an email to either [email protected] or [email protected] if I don't reply promptly (sometimes outside emails get into spam filter's abyss). We tend to move slower with Symfony versions in our main project, but we'll be more than happy to help here and drop our forks

I also have a fork, to make it easier to maintain it only works with Symfony 6.4 :

https://github.com/survos/SurvosLiformbundle

I forked from your fork, but then created a new repo for it since it had diverged quite a bit.
