This alone '"reservations-out-of-pool": true', is equivalent to
setting all 3 of those as you show. And those are the replacement
arguments for "reservation-mode".

You might want to share more of your configuration (you would have
been a lot further on a lot sooner had you done so earlier).
One distressing part of Kea, at least for the version I'm running and
using my limited knowledge (I started my first Kea install 3 weeks
ago, so I'm still learning), is that it does not do DNS lookups to
assign reserved addresses.
With isc-dhcpd one could use:
fixed-address a.b.c.d;
or
fixed-address hostname.example.com;
either worked just fine.

With Kea one needs:
"ip-address": "a.b.c.d"
as using the hostname
"ip-address": "hostname.example.com"
simply does not work.

Really quite annoying as with isc-dhcpd one could simply update the
static DNS ip assignment and the host would get the new address. Now
one needs to update the IP address in the Kea reservation and then
update the DNS server as well if DNS name resolution is desired.
