I strongly disagree. Nothing is worse than developers being forced to work in a language they are not used to - not just because it's inefficient, but because they won't write it in an idiomatic way.
If all you have are TS developers, writing a CLI in TS is not just fine, it's the right decision. Forcing Rust upon them is not going to make anyone involved more happy.
