Yes, that could be done. But I don't think it's correct to say that
the partition holds default values. Let's back up and ask what the
word "default" means. The relevant definition (according to Google or
whoever they stole it from) is:
a preselected option adopted by a computer program or other mechanism
when no alternative is specified by the user or programmer.
So, a default *value* is the value that is used when no alternative is
specified by the user or programmer. We have that concept, but it's
not what we're talking about here: that's configured by applying the
DEFAULT property to a column. Here, we're talking about the default
*partition*, or in other words the *partition* that is used when no
alternative is specified by the user or programmer. So, that's why I
proposed the syntax I did. The partition doesn't contain default
values; it is itself a default.
