Standard compliant code is hardly a taint.

Hyperbole aside, I agree with your sentiment.

Right. Boost is much less about long term support than it is about advancing the state of the art in C++ library design and standardization. Accommodating users of older compilers has always been up to the individual library author. Conditional compilation is a pain they must choose to incur and endure. If you want a library to add support for your platform, it's up to you to encourage the library maintainer to add support or to contribute patches in the hopes the maintainer will adopt them. There is no other option.

You're asking that no C++11-only library -- despite passing the review process -- be permitted in Boost solely on the grounds that it doesn't support your platform or that it will ease the development and maintenance of other libraries which will then no longer support your platform. Older platforms are deprecated either by consensus or attrition. If you have one of those platforms, you necessarily must use an older version of Boost. I have several of those to support. My preference is to push ahead those languishing on older platforms. That reduces the number of platforms I must support both in terms of building my libraries and applications and in ongoing maintenance. Why should a *volunteer* organization like Boost be expected to do anything different?
