I tried it on my router right after I posted the question, here it goes:
ip dhcp excluded-address 172.31.129.1 172.31.129.10
ip dhcp pool hostpool
host 172.31.129.11 255.255.255.0
hardware-address 1111.1111.1111
ip dhcp pool netpool
network 172.31.129.0 255.255.255.0
r8#sh ip dhcp binding
IP address Hardware address Lease expiration Type
172.31.129.11 1111.1111.1111 Infinite Manual
172.31.129.12 0063.6973.636f.2d30. Mar 10 1993 03:43 PM Automatic
3030.312e.3936.6239.
2e63.3865.302d.4574.
302f.30
So no need to exclude the host pool. DHCP server record it as manual binding
already.

Hello Connie,
I would say that you do need the host address to be excluded, becuase
otherwise the dhcp server will assume that al ip address in the address pool
subnet area avail for clients.
Here is additional documentation:
The DHCP Server assumes that all IP addresses in a DHCP address pool subnet
are available for assigning to DHCP clients. You must specify the IP address
that the DHCP Server should not assign to clients. To do so, use the
following command in global configuration mode:
Sincerely,
Matijevic
