Installation from source vs prebuilt packages

Some of the other asdf plugins seem to install prebuilt packages if they exist (nodejs, golang), and I'm wondering there is the intent to do this for ruby (similar to rvm's installation). The primary reason I'm asking is that using asdf on travis-ci is extending our build times by ~3.5 minutes due to the compilation.

No files or tests are identified. Compare how the existing nodejs and golang asdf plugins install prebuilt packages, then determine whether a Ruby equivalent is intended and how it would affect Travis CI's compilation time; done would require an agreed implementation scope and validation of shorter builds.
