I think that belongs to the possibilities. Not sure if the
functionality is there yet though.
If you have a way to trigger "no longer needed", systemd can indeed
shut down mysql and keep the socket alive to activate mysql again on
connection. It's just the "no longer needed" part that I think you
have to do yourself.

No need to rush. Maintaining 2 branches for some time is not that
hard, as there don't seem to be a lot of changes to service-configs
anyway.

I just started converting some services I maintain / use.
My todo list (for the moment) still contains postfix, openvpn
(including "instances") and probably resolvconf with units per
interface.

I suggest you just do something similar and pick other services.
Mysql comes to mind. I don't use that very much.

After the services have been converted, I think we should make a list
of current startup tasks nixos has scripts for that can be replaced by
default (c) systemd tools.

But don't rush of just yet. Let's hear what Eelco has to say about his plans.
Not sure if he agrees with replacing preStart with systemActivation
and adding the low-level options I did.
