You don't need a different image for different manufacturers' platforms. One Linux image works across vendors. The standardisation effort started some years ago resulting in SBSA/SBBR, which allows a common image to be used.
I really want to see someone attempt an Android Treble-like project for ARM Linux distros.
I just wrote a Device Tree Overlay for a Real Time Clock module on FreeBSD RPI3. There is something to be said for PNP hardware.
Who would imagine that the computer industry would go so far back in time as to leave off the RTC.
Oh but wait they added Bluetooth and Wifi. Yet no system time. Still waiting for a PCIe bus as well... Guess I need some more of that koolaide they are drinking.

RPI3 is not a 'server grade' ARM -
See e.g. the AMD 'Opteron A' boards:
http://www.lenovator.com/product/103.html#params
CPU Quad-core ARM Cortex-A57 64 bit
DRAM Two DDR3 SO-DIMM sockets
SATA Two SATA ports
USB Two USB 3.0 ports
Console USB-micro port for console support
Ethernet 1 GBe Ethernet
PCIe x16 PCIe G3 slot
5+ years on, ARM on anywhere but mobile seems like a dud.
