[Bug] Heatmap Axis "time" and "value" type behavior is different between development and production versions

[Seymur]

Version

6.0.0

Link to Minimal Reproduction

https://codesandbox.io/p/sandbox/5swcrj

Steps to Reproduce

1. Add Heatmap type series
2. Set xAxis / yAxis types either to value or time
3. Run it in development mode

Current Behavior

In development mode it throws Heatmap on cartesian must have two category axes error. In production it does not. There is a check in the https://github.com/apache/echarts/blob/master/src/chart/heatmap/HeatmapView.ts file that causes this behavior.

if (__DEV__) {
  if (!(xAxis.type === 'category' && yAxis.type === 'category')) {
      throw new Error('Heatmap on cartesian must have two category axes');
  }
  if (!(xAxis.onBand && yAxis.onBand)) {
      throw new Error('Heatmap on cartesian must have two axes with boundaryGap true');
  }
}

Expected Behavior

It should be the same behavior in both dev and prod modes.

Environment

- OS:
- Browser:
- Framework:

Any additional comments?

If you use it in a way that is not promised or documented, the behavior is not guaranteed.
The limitation is documented here..

Rectangular coordinate must have two categories to use it.

As the name suggests, development mode is for development only.
During development, you can use the non-minified (development) bundle instead of the .min.js file.

I understand there is a limitation how to use Heatmap axis types. But why isn't it enforced in the production mode. I can change axis type to time in Echarts examples editor and it works without any error and shows Date in the axis. Isn't it confusing why there is a difference between dev and prod modes. Last time I spent a lot of time to see why the exactly same code works in Echarts editor and not in my local development environment.
