Proposed resolution:

Change [support.limits] to:

-1- The headers <limits>, <climits>, <cfloat>, and <cinttypes> supply characteristics of implementation-dependent fundamental arithmetic types (3.9.1).

Change [limits] to:

-1- The numeric_limits component provides a C++ program with information about various properties of the implementation's representation of the fundamental arithmetic types.

-2- Specializations shall be provided for each fundamental arithmetic type, both floating point and integer, including bool. The member is_specialized shall be true for all such specializations of numeric_limits.

-4- Non-fundamentalarithmetic standard types, such as complex<T> (26.3.2), shall not have specializations.

Change [numeric.limits] to:

-1- The member is_specialized makes it possible to distinguish between fundamental types, which have specializations, and non-scalar types, which do not.
