Crate term and libterm

Recently, the term crate got new functions and I was wondering if these functions would be integrated in the libterm. I was trying my hands at issue Indicate compilation progress in a form useful to end users · Issue #24335 · rust-lang/rust · GitHub and I am not really sure how to do it without the cursor_up, delete_line and carriage_return functions. I think functions like these would be very handy in making animations in the terminal.

Sorry if it isn't the right place to ask this question but I wasn't sure where to ask.
