Back-Rev Packages (curl, this time)

Are there plans to update the versions of curl, git, etc. in either EL 6 or 7 to be something more closely-aligned with "current"? I've got a customer griping at me that they can't make use of CodeCommit (via instance roles) because the curl versions that ship with RHEL 6 — and even RHEL 7 — are old enough that they don't correctly support credentialed-auth via HTTPS (at least per AWS's reply to a support form thread) . Looking at the RHEL 6 curl version, it's at 7.19.x while RHEL 7 is at 7.29.x ...and I need 7.33.x (or higher: haxx has the current version at 7.50.x)

Background: when providing instance-level access to CodeCommit-hosted repositories, git connections need to be done via authenticated HTTPS rather than using SSH-keys.

Some of this can be worked around by using IAM users rather than instance roles, but that has its own issues (with respect to key-rotation and the like).
