Add automatically compat entry when adding a package

[saschatimme]

Assume I install StaticArrays in my current project

(v0.7) pkg> add StaticArrays
 Resolving package versions...
  Updating `~/.julia/environments/v0.7/Project.toml`
  [90137ffa] + StaticArrays v0.8.3
  Updating `~/.julia/environments/v0.7/Manifest.toml`
 [no changes]

I think that then automatically an entry to [compat] should be added limiting to the current (semver) major version, i.e.,

[compat]
StaticArrays = "0.8.3"

With this, you (as a user or package author) have to explicitly upgrade your dependencies to a new major version and do not run into the problem of an incidentally broken package or script.

Yes, this is the plan for future versions.

Is there any reason this hasn't gained more traction/are there plans to implement this in the near future? :^)

Same question here... Any update on this issue?
