Seems like a bizarre choice of name. Why not "default"?

Don't see why they would. Let's review what we have here:
Database Function(s)
template0 guaranteed-virgin template for CREATE DATABASE
template1 installation-default template for CREATE DATABASE
default database to connect to for clients
(I don't think I'm missing anything --- can anyone think of a purpose
I have forgotten?)
If we split template1's functions as
template1 installation-default template for CREATE DATABASE
default default database to connect to for clients
then it becomes fairly reasonable for DBAs to block access to template1
after they've installed any installation-default stuff they want in it.
There isn't any particular reason to block access to "default", unless
you don't want to have a shared database at all --- in which case you'd
probably just drop it.
One argument against this is that it'd mean another copy of the system
catalogs in a standard installation. That's been running three to five
megabytes over the last few releases. Disk space is pretty cheap these
days, but we do get occasional complaints from people who wish the
footprint was smaller.
