Ruby gem dependency: i18n limited to v1.1.0 ?

[dhempy]

I updated my Ruby app to use signalfx 3.1.0 (from 2.1.0)
 
I was surprised to see this gem downgrade when I bundled:

  Installing i18n 1.1.0 (was 1.8.5)

That's rewinding the i8n gem about two years. 

Looking at signalfx.gemspec, it is locking it in to exactly that version:

  spec.add_dependency "i18n", "= 1.1.0"

Is there a reason for that? It seems an optimistic version such as ">= 1.1.0" would be safe and not so restrictive, and would match most of the other dependencies in the gemspec.

While this is not a blocker for our app, please consider putting in a feature request to relax the i18n version dependency.

Similarly, I notice the signalfx gem restricts activesupport to <6

Activesupport 6.0 was released over a year ago. This is more likely to be a blocker for signalfx clients moving ahead.
