So, that's why we need ULA-C, rather than "tainted GUA".

The ULA-C will *not* leak into the global routing table, because there
will be lots and lots of filters that reject it.

Sure.  Show me again, where the 20-person operation that have a cable
connection, and a DSL connection (and thus two sets of GUA-PA), get this
GUA-PI that they need to have stable addresses internally?
Said company has two different types of connections because neither is
reliable enough.

ULA-C is not about ISPs. It's about SME.
