Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Moonrepo

Smaller community compared to established build systems like Bazel
Limited integrations with enterprise CI/CD platforms
Documentation gaps in some advanced use cases
No commercial support option for organizations requiring guaranteed SLAs

RubyMine

No permanently free tier for commercial use; requires an ongoing subscription.
More resource-intensive than lightweight editors such as Sublime Text.
Focused primarily on Ruby, so polyglot teams may prefer IntelliJ IDEA Ultimate with plugins instead.
Startup time can be slower than simpler text editors on older hardware.
