I know that Rust can have a bit of a learning curve, but it is also extremely reliable, especially when taking contributions from all kinds of people as different changes are unlikely to slowly break each other over time.
I would for example be extremely cautious when it comes to dynamically typed languages like Python. If you think bad Rust can be verbose or complicated, you’ve never seen bad Python. It can devovle into a mess very easily due to the lack of static analysis.
Also Rust has great performance which is important for keeping operational costs low. Corporations running Python just eat that cost because it’s nothing compared to an engineers salary but operational cost will be everything when it comes to a volunteer run service.
