Request to export GccParser and ClangParser

This is follow up to my question on ml
ProjectExplorer::GccParser not exported?, whereas GnuMakeParser is exported.

I received answer that

Symbols are typically exported on an as-needed basis. If you have a
sensible use case, formerly private things can be made public (...)

I would like to argue, there is 'market' for those parsers and plugins like managers for new build systems could happily make use of those.
An alternative is to copy those parsers from Qt Creator codebase into a plugin codebase, which is not optimal for long term maintenance.

For example, I started developing a plugin to add Boost.Build support:
https://github.com/mloskot/qt-creator-plugin-boostbuild
where I use GccParser, ClangParser and LdParser, and in future I'd like to use parsers for all toolsets supported by Qt Creator.

So, it would be helpful if there was a tradition of exporting the concrete parsers.
