> many people pushing for Rust

You have couched this correctly, because we all know there are people out there who do go around yelling "Rewrite it in X" without thought (where X is the flavour of the month)

I also wanted to say - your description of the /right/ way to align a project with tech X is a restatement of Martin Fowler's "Strangler pattern"

Can you edit your post - "equation because deteting errors" is ambiguous - deleting, or detecting - I cannot work out which you mean
