I see. My logic is this: from the below:

3 In addition, some identifiers are reserved for use by C++
implementations and shall not be used otherwise; no
diagnostic is required.
(3.1) — Each identifier that contains a double underscore __ or begins
with an underscore followed by an
uppercase letter is reserved to the implementation for any use.
(3.2) — Each identifier that begins with an underscore is reserved to
the implementation for use as a name in
the global namespace.

I make 2 conclusions:

A. some identifiers (in particular those starting with _) shall not be
used by otherwise than by C++ implementation
B. If an identifier starting with _ not followed by an uppercase letter
is used by C++ implementation, it should be used as a name in the global
namespace.

From that it follows that:

- bonitas::_ is not allowed because of A.
- if A. did not exist, it would be still not allowed because of the
clause Alf referred to in his recollection of the Standard, namely:

Identifiers starting with `_` are reserved in the global namespace.

What I am  missing?
