To be clear this is all just my opinion, I am not a Solus team member.
My understanding for ARM is that it is not standardised to the point you can simply support booting on all ARM devices. In which case I highly doubt they would waste their resources on such a small portion of the market. But who knows what the future holds, I think everyone is excited about ARM's potential.
I have a RPi3 and love it. But I would not put that in the same category as Solus's target market at this stage.
