Well Python 3 came out in 2008, this date is known since 2014. If they start in the next few years, yes you'd expect it to be expensive.
But distribution vendors like Red Hat and Ubuntu have Python 2 in long term support distributions that they will give support for a few more years, so it is possible to use those. And after that they offer more years of support to paying customers. It's not necessary to hire programmers to do this for the companies needing support themselves.
