Who's working on a "smaller Rust"? (programming.dev)

Almost five years ago, Saoirse "boats" wrote "Notes on a smaller Rust", and a year after that, revisited the idea.

The basic idea is a language that is highly inspired by Rust but doesn't have the strict constraint of being a "systems" language in the vein of C and C++; in particular, it can have a nontrivial (or "thick") runtime and doesn't need to limit itself to "zero-cost" abstractions.

What languages are being designed that fit this description? I've seen a few scripting languages written in Rust on GitHub, but none of them have been very active. I also recently learned about Hylo, which does have some ideas that I think are promising, but it seems too syntactically alien to really be a "smaller Rust."

Edit to add: I think Graydon Hoare's post about language design choices he would have preferred for Rust also sheds some light on the kind of things a hypothetical "Rust-like but not Rust" language could do differently: https://graydon2.dreamwidth.org/307291.html

Coming from some one who used 4 different languages (C#, C++, Python, and G'MIC), I just feel more comfortable when there's a explicit end blocks, which is why I don't like Python. Of all of those languages, only Python does not make that explicit end block which is off-putting in my opinion, and there isn't any other options with the similar role to Python.

Ruby often comes up as a python alternative. There are a lot of other lesser known choices - but any of them will still be more popular (at least at first) than something you come up with and thus any of the will give more community support.
