If you want me to support your use case of compilers more than six months old, you need a better damn reason than "I don't want to upgrade my compiler". The v3 resolver handles MSRV ffs.
I am sure as hell not rehashing an issue when I am not in a good headspace (as is the case now). There's far too much going on in life to deal with this shit. If you want special support, talk to me and we can set up a binding contract. Until then I'm deleting this type of issue outright.
