I'm not sure I'm following your question exactly, but...
It seems to me it goes like this.
In stock-dhcpd, you can have the situation that, say
host has a lease it got when it presented a uid
host boots w/o a uid and can't get a least because
"no free leases"
<or the other way around.>
Hence the value of the 'evil standards-non-compliant' ignore
the uid patches out there -- it looks like the same host no
matter if sends a uid or not and regardless if the uid value
changes or not.
Obviously this has some shortcomings for some uses as well
(perhaps you want to dual-boot O/Ses and get different values
you could do that through sending different uids).
