I use the system Ruby and don't have to worry too much about rbenv and rvm. 2.7 and even 3.0 is well supported. That's what I also did with Perl, except when I used MacOS which was a pain because of modules that used C libraries like LibXML. On Linux we can also use containers without worrying about speed penalty. There are sufficient solutions and okay tooling. Ruby's also got not one but two JIT compilers right now.
