What libraries (moxy/mosby) are still used in real applications?

Question

Android

Good morning, good afternoon, good evening!
I want to know if moxy/mosby are still used in real applications? I myself have never come across these libraries, what they do has always been implemented manually. A year and a half ago, they were written about everywhere, everywhere they were required, and without them you are not an android programmer at all. Now, no one seems to be saying that these libraries are outdated, but for 2018 there are really no publications in Google. Yes, and according to the requirements of vacancies, I looked - moxy is still required in a certain number of vacancies, mosby is practically absent (for example, on HH - there is a mention in only two vacancies). And are they generally used in serious applications? I couldn't find almost anything on google.
