I think it's somewhere between what you wrote, and they don't trust the crappy 
temp cable connection over there at the site.
They say what if the VPN goes down - users won't be able to get ips if a 
machine reboots!
I say, what the hell are they going to be doing anyways if the VPN goes down?

I think your admins dont understand what dhcp relay is, im guessing they thing 
the relay is a weird way of saying its a l2 tunnel for dhcp or some dumb shit. 
other than the loss of dhcp when the vpn is down, relay would be the preferred 
way to do it. I dont know how mikrotik works with secondary relays, but you 
could configure the primary to point to the AD DHCP server, and the second 
being on a virtual interface of the mikrotik, since its just relaying to itself.
Go online and find a 6 pack of Jolt Cola, give that to the sysadmin, he will 
let you do what you want.

Indeed, this is a corporate setup with Windows DHCP at the core.
This is a site on the remote end of a VPN.
The sysadmins were a bit on edge about sending DHCP across the VPN, so they 
asked that we stick it local on the remote site Mikrotik router....which works 
ok, though we hit a bit of a snag with the NAC, which likes to sniff DHCP 
traffic to help detect and identify devices on the segment, in addition to 
several other data sources.

I may just nag the sysadmins to build this out in the core DHCP and this will 
solve itself.
Just point DHCP Relay at both addresses and I think we'll be fine.
