> whether there are also potential users who would have been perfectly happy with javascript/python/R bindings and a good tutorial

If you think people in some communities would benefit then you should be proactive in advertising there and in particular providing bindings for their favourite languages. This would enhance discoverability. In my corner of the tech and science world, people mostly use python and/or R but few know about Rust and fewer have knowingly used it.

The architecture of DDflow does not lend itself well to bindings of the common, interactive type. It relies on the code for the operators being compiled and optimized by LLVM, which inhibits run-time configurability.

Nah, materialize is basically interactive SQL bindings for DD. There is some loss of optimization potential compared to running everything through the rust compiler but it's still decent.
