Not to discourage you but the things you pointed out aren’t really an issue.
IPv6 is a replacement for ipv4 but no one wants to fix what isn’t broke just yet. Maybe that’ll change when we run out of ipv4 addresses, which is what ipv6 was supposed to solve.
The bug you pointed to Is because the code base wasn’t designed to fall back to ipv4 when ipv6 was disabled on the receiving end. You can see that reflected in the commit you linked where the variable was replaced with a function call.
