How to configure the DHCP to make a priority between the subnets inside same shared network

What's wrong with that, and why would it break? I would also have a lot
of use out of a 'priority' block, with a 'backup' block. In the past, I
had a block that was too small, with a NAT block to increase the useful
size until I could get new allocations from ARIN. Now that I'm done
with that situation, I would still find a 'backup' block useful, though
not as much as before.
I never posted a thread about it because I found on in the archives
saying why it wasn't implemented, but I think it's a valid feature
request. As long as addresses are assigned according to RFC in the
'primary' block, what would it hurt to implement this? Maybe set a
longer lease time on the 'primary' block, and a short one on the
'backup' block. If a device renews the allocated address before expiry,
it's renewed, but if that client reconnects after the lease with a
DISCOVER, it gets allocated an address from the 'primary' block if there
is one available. If there isn't a primary address available, it gets
reallocated the same backup address it had previously.
