The project I wrote and and have supported for the last 23 years is on most
or all linux computers and also (in a very early version) on all mac
computers. It's kind of hard to tell how many users there are. I've gotten
exactly $0 from my efforts. On doesn't undertake volunteer work with the
expectation of getting money out of it.

I have no idea how this sort of cash award affects developers. I mean, if
the developers have day jobs then offering $50 for a feature that takes ten
hours of work is sort of insulting, since it means $5/hour. There are
studies done about how offering money for things can shift perception and
behavior as it moves the behavior from a friend interaction to an economic
one. (Do you offer your friend money to help move a piece of furniture?)
Of course, if a developer does not have a paying job perhaps getting $50 is
a big draw. And I wouldn't suggest that people don't offer money if they
choose. But ultimately, working on a project like mine, or like OpenSCAD is
volunteer work, and one must choose to do it for the interest, enjoyment,
and/or feeling of making a contribution to the community.
In the case of OpenSCAD, there's no roadmap that I've seen describing which
features the developers are interested in actually implementing. In my
experience, if I have an idea of how the program might be improved and I
suggest it first it's met with a kind of hostile reaction about how I
shouldn't expect anything, and secondly, it's already been suggested many
times by others. I found what seemed to me to be a major bug and discovered
it was already reported and had been open for years. So all of this makes
it seem like change is unlikely. This is an observation, not a criticism
of the developers. And it doesn't make a whole lot of sense to wait around
for the 2023 release.
That's why the question is: what does OpenSCAD do now, so I can use it best?
How does multmatrix() work? How are we supposed to use it? I didn't start
this discussion to be a debate about OpenSCAD development, but rather to
figure out how I can and should use multmatrix(). And also possibly I
thought I might improve the manual to better describe how multmatrix()
works, since that's something I *can* do to help others. But it looks like
maybe this effort is also not appreciated, or is controversial---the
response that seems to arise for all efforts to help the OpenSCAD project.
So I guess I won't bother. It's pretty hard to make a contribution.
