mailing list manager for 4.7?

I was looking for a working list manager for 4.7. There doesn't seem to be one. phplist, mlm, ezmlm, mlist all cause errors at various stages in a clean 4.7 install.

is anyone working on such a 4.7 module? i see a couple of the above modules have 4.7 tags, but they still don't work.

would this be considered the homepage for any such effort?
