Validator for publishing rate

[jonasfj]

Proposal:

If you've published more than 5 versions over the past 30 days, then publishing validations throw an error.

This can be ignored with --skio-validation.

We can fetch versions from the API, which has a published date-time.

It's a simple way to limit publishing without making a hard limit. Also we can put in a message pointing to dart.dev/go/publishing-frequency. Then we can document guidelines for publishing rate, and document out limits.

Let's start by writing dart.dev/go/publishing-frequency. It will add value on its own

We should probably make this a warning only...

I'd be down for having two rate-limits:

• Error at:
  • 20 publications past week (20 versions/week)
  • 32 publications past month (~ 8 versions/week)
  • 50 publications past 3 months (~ 4 versions/week)
  • 100 publications past year (~ 2 versions/week)
• Warning at:
  • 15 publications past week (18 versions/week)
  • 24 publications past month (~ 6 versions/week)
  • 60 publications past 3 months (~ 5 versions/week)
  • 75 publications past year (~ 1.5 versions/week)
