Ulrich Drepper (former glibc maintainer) states: Every DSO used increases resource usage. As the DSO How-To points out, loading a DSO isn't free. There is usually measurably more memory used. The calls into the DSO are more expensive than normal function calls. And a lot more. Link: https://udrepper.livejournal.com/8790.html I would honestly love if more ext (mainly socket, but also fcntl, etc) were in core, too. However, I do suggest keeping empty placeholder .rb files indefinitely to avoid breakage when distros update ruby. Some users have scripts in ~/bin running unmodified going back over 20 years.
