Serious question. Is the committee ok with just adding features forever or do they realize they have to stop at some point?

Unpopular opinion: Just use C(99)

  I can't. My company doesn't allow me to use whatever languages I want and my experience is in a niche industry.

Programming languages are products. There is no product that is done, and keeps being used ad infinitum. By the way, C23 just has been ratified, last COBOL standard is coming this year as well, and Fortran was last updated in 2018.

  I realize this. But C's new feature lists get smaller and smaller and are a lot more sane. https://en.cppreference.com/w/c/23 https://en.cppreference.com/w/c/23 Meanwhile C++ just added for loop scoped typedefs. for (typedef int Points; Points points : pointsScored) { std::cout << "Jokic scored " << points << '\n'; }

    Just wait for what was left out of C23 and planned for a later revision, https://thephd.dev/lambdas-nested-functions-block-expressions-oh-my https://thephd.dev/lambdas-nested-functions-block-expression... https://thephd.dev/c-the-improvements-june-september-virtual-c-meeting https://thephd.dev/c-the-improvements-june-september-virtual... https://thephd.dev/ever-closer-c23-improvements https://thephd.dev/ever-closer-c23-improvements Only a small overview, I lost the link to the PDF with the whole set of language proposals for C2X.

    They do also deprecate and remove stuff too, and not all new versions are large (C++14 was very small). So, sure, they found a bunch of new stuff to add, but the frequency and size of updates does seem to depend on how much stuff is proposed that they deem useful enough to add. Note that in the time C++ had 5 updates, Python has had 10 releases and Java has had 14!

For this particular "deducing this", it is actually removing unnecessary corner cases due to a wrong historical decision that made "this" parameter available only in an implicit way. Probably you may want to read the article before expanding your own narrative?

People complain about the breadth of C++, but the reality is that you don't need to adopt new versions, and regardless of what version you use when compiling code you should have an internal style guide dictating what features are permitted, which are not, and which features are only permitted in specific circumstances. For example, Google is switching from defaulting to -std=c++17 to -std=c++20 later this month, but most of the major C++20 features (e.g. ranges, coroutines) will be prohibited. And there are a lot of major C++ features that the Google internal style guide does allow but discourages people from using unless they have specific needs.
