Hello,

I have checked the presence of "ss" on SuSE Linux Enterprise Server 11. This system was release in 2009. And there is "ss" on such old system. As far as I remember, I started to use "ip" over 15 years ago. I haven't met any system without iproute2 package installed for last 10 years. You can make your own check to confirm this. Probably there is no need to make any additional logic for backup compatibility. Probably there are "ip", "SS", "routel" commands on all systems.

Beginning to feel the same way as well, FWIW.
