Adding arch support for hibernation to arm64 should be fairly simple,
it is not top priority at the moment simply because there are not
compelling use-cases (on the PM side most features revolve around
CPUidle and suspend-to-idle and S2R).

To answer your question, yes I have planned to support it, I just
do not want to add it to the kernel for no particular reason, if there
are compelling requirements (I guess you are asking for a specific
reason) it can be done fairly quickly.
