When introducing the original staking limits: #8920

we were a bit too strict on the behaviors allowed during otherwise okay scenarios.

The following changes are made in this PR:

  • If we are not within our max nominator / validator threshold, we do not allow anyone to call chill_other on a different user.
  • If we are an existing nominator / validator, we can still update our preferences using nominate / validate

polkadot companion: paritytech/polkadot#3376

Should the origin param for chill_other be configurable for the pallet? (I believe @shawntabrizi mentioned this idea already somewhere)

The current, permission nature of this call is useful for scenarios where we want a network to be continuously "self adjusting". But I think we can imagine scenarios where this makes more sense as a governance only call (that then can be turned into a permission-less call with a runtime upgrade).

While I don't see how it would improve security properties, I think having a call like this go through governance could benefit the community

Tagential, is it possible to make a call origin configurable without a runtime upgrade?

Nope, that's logic change and needs altering :code.

+1 :)

Outside the goals of this PR, I am curious if it is worth looking into a governance origin for chill_other; see #9193 (comment)
