Although to make things less confusing, I think the built-in language

the built-in one would certainly be less trouble, as code doesn't refer
to it by its name, and you can pick a name that fits better with its
auto-expanding behaviour.
Not referred to by its name? It's refereed to as TypeTuple all over the place.
It's arguably a bad name, but it would break a _lot_ of code to change it now.
TypeTuple is only a construct allowing you to create a built-in
language tuple, one that does not necessarily match the definition of a
TypeTuple. The language spec defines a Tuples, TypeTuples, and
ExpressionTuples with these words (ironically, using the word
"sequence" twice):
"""
If the last template parameter in the TemplateParameterList is declared
as a TemplateTupleParameter, it is a match with any trailing template
arguments. The sequence of arguments form a Tuple. A Tuple is not a
type, an expression, or a symbol. It is a sequence of any mix of types,
expressions or symbols.
A Tuple whose elements consist entirely of types is called a TypeTuple.
A Tuple whose elements consist entirely of expressions is called an
ExpressionTuple.
