In my networks I use a combination of ULA's + SLAAC for anything that needs to 
behave like RFC1918 and disable address privacy so that the IP remains static, 
and for internet routable they use the prefix learned from the provider and 
propagated via SLAAC.

The only current RFC on ULA is fc00::/7 but fc00::/8 remains undefined and has 
not been accepted by IETF. The block fd00::/8 can be divided up.  All of this 
said none of these addresses would be routable on the internet and since a lot 
of the end user equipment can't handle a statically configured ULA address and 
still obtain a routable address from SLAAC or DHCP6.  This creates major 
problems for networks with limited IT support.  On larger corporate networks 
with skilled IT people it's very likely that they will have a static allocation 
from an ISP however smaller networks without IT people it can become a serious 
problem.  Those people won't be skilled enough to figure out ULAs anyway.

Those were site-locals, not ULAs.
