Well, no; it compiles all unittests of all *compiled* modules,
not all *imported* modules. So it does not actually include
Phobos unittests.

As Steven Schveighoffer [pointed out][1], Phobos unittests are
never included in user code, regardless of whether
`StdUnittest` is used.
The "never" is false, https://d.godbolt.org/z/c4oeYM7rG
Unittests inside template code will be added to user code, unless
the compiler has determined that the template is already
instantiated in Phobos code (the "template culling" that the
frontend does, whose behavior is not easily influenced by the
programmer).
