Well, yes and no.  As $newer_better_faster_stronger gains market share, there's no drive to be backwards compatible.

iOS is no different from any other operating system in that regard, it's designed for hardware A, B, C, D's 1 through 4 (probably more, but I'm trying to be somewhat abstract).  If it has to support E through Z also, for 12+ years of backwards compatibility, bad things can happen (bloat, instability, bugs).
I don't get upset for example, when I transplant a Win2k or Win98 drive into a box built up with 3 year old hardware, of which not a single device is supported.
That's not even taking into account the challenge of developing for different architectures. ARM, x86, PPC, AMD64, PowerISA, SPARC, to name a few. I won't even get into microcontrollers.

Don't get me wrong. I'd love to update my 12 year old Macbook Pro to Sierra, but I've accepted that it, like most electronics, were almost certainly not engineered, let alone expected, to last even half that long.
I'm reminded of that fact every time I open Youtube, and Flash Player spins both of its 2.33ghz Core2 Duo cores to 100% for a 460p video.
Even then, I've had to stop updating Flash sometime around mid 2014, as any newer versions cease to function entirely.
