MPIR, a fork of GMP, has not been updated upstream. The latest release, 3.0.0, is from 2017-03-01 (https://mpir.org/downloads.html).

Sage currently provides an SPKG for MPIR as a configurable alternative to GMP. We should remove this option and package, as previously suggested in #29620 comment:10

Depends on #30350
Depends on #31163
