To be fair, I completely understand your view as I used to share it. Users
of C++ are certainly frustrated by the apparent opaqueness of the
standardisation process.

There is a counter position, that C++ has only survived because of the time
and effort put in by the individuals who make up the “committee”.

Most of these people care deeply about the language. Often to the extent
where progress is not made in case of “acting in haste, repenting at
leisure”.

Not all of these people agree with each other on all design and
implementation decisions. Or even for that matter on whether a feature
should be in the language.

I think that one of the benefits of the headless, collegiate approach is
that matters get discussed thoroughly and the overall discipline of
computer languages is furthered (although sadly often behind closed doors,
so the wider user base do not witness and therefore benefit from the
knowledge gained during these sessions).

One of the downsides is that there is no firm leader who can say, “the
users have spoken - they shall have their feature”, which is entirely
possible in a proprietary language owned exclusively by a huge corporation.

Also there is no way for the user base to communicate the features they
need to WG21, other than writing a paper - which is a specialised skill in
itself.

It’s important to understand that writing compilers is not a
profit-motivated activity.

(Almost) nobody has paid for a compiler since the turn of the millennium.
Every program you compile is courtesy of some individual or corporation who
chose to donate time and/or money.

For this reason, there is no fundamental driver for providing “customer
service”. Customer service is a tool for gaining competitive advantage in a
contested marketplace. It’s not a fundamental right of humanity.

Out of interest, what feature do you think c++ most sorely lacks?
