I don't think reproducability will be actually hurt, you can always download an old copy of python 2 somewhere (there are places that archive p2) and run the code. Unsupported doesn't mean the software version implodes into vacuum. It just means if you install it, it'll be a rather ancient version that has possibly many bugs and vulnerabilities and you should probably not have that touch production.
