in what packages do you use particular options for re-recording @sckott ? It'd be nice to mention use cases.

[sckott]

There's apparently a lot of use of the re-record interval in Ruby vcr usage - https://github.com/search?q=language%3Aruby+re_record_interval&type=code - It should probably be considered best practice to re-record every so often - but the details of that I'm not sure yet. One thing is, you provably do not you want re-record'ing to happen on your CI system or on CRAN. How is that handled?

I don't actually do it yet in my own pkgs, but i'll start playing with it
