We are going to use "Giesecke & Devrient GmbH StarSign CUT S" which is supported since ccid 1.4.24. Currently used in LTS 16.04.2 is ccid 1.4.22. I couldn't find any roadmap for the next LTS releases.

The Artful Aardvark (active development) Ccid trunk series: 1.4.27-1 release (universe)
The Zesty Zapus (current stable release) Ccid trunk series 1.4.26-1
So the current normal release (17.04) already uses 1.4.26 and the next normal release (17.10) is going to be using 1.4.27.
Unless there is something unforseen (like the maintainers stopping development) the next LTS (18.04) will be using at least 1.4.27.
16.04 will stick to 1.4.22 but you could install 1.4.24+ yourself: the dependencies are the same for 16.04 and 17.04:
libc6 (>= 2.14) [amd64]
libc6 (>= 2.17) [arm64, ppc64el]
libusb-1.0-0 (>= 2:1.0.9~)
Version numbers are the same so installing the DEB from 17.04 on 16.04 will not be a problem.
