The end of "full support" for RHEL 7 is "~Q4 of 2019". After that, there's "Maintenance Support" until 30 Jun 2024 but that only includes "errata", which are "provided at Red Hat's discretion" -- and specifically excludes "Software Enhancements" ("additions of new functionality beyond correcting defects ..."). I expect that after Python 2's EOL, we'll see very little in the way of updates for RHEL 7's Python 2 packages. There just won't be that much for them to do.
