The proposal will upgrade the nomination limits such that more people can start nominating. Note that this is a time-sensitive action, because currently existing nominators cannot change their intentions. [This pull request](https://github.com/paritytech/substrate/pull/9193) will change this logic, so that those who are already a nominator will not be affected by any limit, and **will be placed in the next Polkadot  runtime upgrade**.

The new limits increase the nominator capacity by `2500` (making it `22500` in total), and increase the the stake threshold to `40DOTs`. It is intended that these numbers would keep the current count of nominators (all of whom must have 40 or more DOTs) below the new count limit (`22500`) **until the next runtime upgrade**: If an influx of nominators is observed over a very short period of time, the stake limit might need to be increased again proportionally to keep the staking system stable.
