For future release, a better way of handling this will be needed. The fact
that these updates break random other packages isn't really acceptable.

This is not realistic at this point.

I don't know if there is a good way to track al these dependencies. With some
effort, I got to this list of packages to remove:

rust-bytecount
rust-coresimd
rust-encoding-rs
rust-encoding-rs-io
rust-grep
rust-grep-printer
rust-grep-searcher
rust-packed-simd
rust-ripgrep
rust-simd

I guess the only option is to remove all of them from buster.
