Which versions? Do you know how many older versions of both are actually in
I'm not trying to be flippant. The thing is, I have to write HTML
therefore have some experience with what it really takes to do that in a
"portable" manner. And in my case we have the option of requiring the use
of a subset of browsers/versions. We still get the maintenance complaints
that the apps are broken and/or display poorly and have to spend time
diagnosing that the user is running an unsupported browser/version.
With Boost, this is much worse, since we don't (can't/won't) specify what
browsers/versions are supported, and our documentation should also "play
nice" with non-browser utilities which are VERY likely to not support JS.

I don't see that as true. Boost is actually pushing the evolution of some
things. For instance, Boost.Build is pushing the evolution of software
construction beyond the simple make.

Yes, we care about standards, but we live in reality. For instance, look at
how much effort is put into making libraries compliant with compilers that
don't meet the standards. In this specific case, JS simply isn't portable
enough, standardized or not, and since Boost's focus is on C++ library
development and not HTML, it's more pragmatic to simply limit the use of web
standards to the strictly portable subsection. If we don't do that, we'll
spend way WAY too much effort on fielding complaints and tweaking the

I never claimed presentation didn't matter. I claimed usage statistics
didn't matter. Different argument totally. Even if 99.999% of every user
was running IE on Windows XP, that would still be irrelevant, since there's
still users using something different. Boost documentation has to be
maximally portable, not just usable by the majority.
And don't forget that there's more to this argument than just presentation
in a browser. Users will run the HTML documents through all kinds of
utility programs as well.
