"The following default gems are now bundled gems." Great to see slow removal (or carve out) of rarely used stdlib stuff.

Ruby would benefit from a trimmed down stdlib, where effort could be spent keeping a smaller footprint stdlib more polished than it is today. Turning them into opt-in gems is a good first step.

A few examples:

- `rss` to parse RSS documents/streams

- `win32ole` for Microsoft Windows OLE Automation

- `dbm` for DBM databases

- `abbrev` for finding the shortest unique abbreviation amongst many strings
