While some people may think C++14 doesn't provide enough bang for the buck to justify bumping to GCC 4.9, C++17 definitely does. But at that point we're going to be talking about GCC 6.1 or 6.2, which is going to be significantly harder unless we want to wait 5-7 years, and I suspect people won't.<br class=""></blockquote><div class=""><br class=""></div><div class="">If by "notoriously slow" you mean they don't bump their toolchain versions at all, then yeah.

I just meant we support the last LTS until we can reasonably expect users to have upgraded to the new one.
