Yes. You'll find the case sponsor announced ...
"Based on the valuable feedback, the two projects have agreed not to
co-locate their files under /usr/compilers."

It does allow the same ... this case says:
4. Technical Description:
4.1. Details:
- The design of the Sun compilers precludes just installing
them into /usr/bin, /usr/lib, etc. without significant
redesign. We need a location into which to install the
compiler components, with symlinks to those components
installed in /usr/bin and /usr/share/man. The delivery will
install the bundled compiler collection components into
/usr/compilers/{bin,lib,...}, with symlinks in /usr/bin and
/usr/share/man. We chose the name 'compilers' to
intentionally indicate these are the
default|builtin|preferred|bundled compilers. There will not
be multiple versions, there will only be one set of bundled
compilers. Versions of the unbundled Sun Studio will
continue to install into /opt, i.e. /opt/sunstudio13,
/opt/sunstudio14, etc.. Note Sun Studio also provides an
optional package for installing links in /usr/bin and
/usr/share/man, these would then override the links of this
bundled compiler as it does previously installed versions of
Sun Studio.
