Which is what I argued in the original thread(s): the name is
misleading - nothing more.  The macro is (was, before this change)
about a help buffer, not about an arbitrary temporary buffer.

The right way to make the desired change is to introduce a new,
non-help-mode-related macro and use that where desired, not to
gratuitously change the behavior of the longstanding macro
`with-output-to-temp-buffer'.  (And preferably rename the latter
using defalias, so that the new name indicates that it is about
help mode - e.g., `with-output-to-temp-help-buffer'.)

As just one user, this unfortunate change caused me to make
version-adjusting code to handle it, in multiple libraries of mine.
Not a big deal, but it should not have been necessary at all.

However, Glenn, it seems this was already decided, with Eli, Stefan,
and Martin unpersuaded by my (and apparently your) argument.
