I'd hope to allow competition. But if you think developing high quality
C++ code is expensive, then developing high quality storage code is
considerably more so. I think recouping the cost of development is very
reasonable, after which it can be open sourced.

Profit and open source are not in conflict. If anything, especially in
recent years, there is plenty of profit in open source. I, and many
others even on here, make a living from it.

I'm also mindful of Anthony Williams' Just Threads! which is effectively
a v4 complete rewrite of Boost.Thread. That's a commercial product held
totally separate to Boost, and it has been woefully underused because
people didn't know it existed. Some would argue - and I'm not sure I
include myself here - that if Just Threads! were the all new singing and
dancing Boost.Thread rewrite, and if people running into problems with
Boost.Thread could pay the fee for the new rewrite until its development
costs were paid off, that could bring new very high quality developed
for profit libraries to Boost.

As I said, I'm not sure I agree with that myself, lots of slippery
slopes in there. But equally I've seen old versions of big games engines
released to open source after they no longer make money, and that's been
a *huge* benefit to open source. So the model can work, and work very well.
