If I have understood you correctly, you are suggesting to remove [this check](http://git.io/WfYFBQ). This is not a simple task, because erchef will also need to be modifier [here](http://git.io/hFWKFA).

Using the following metadata with a modified chef-client:
```
# metadata.rb
supports 'ubuntu', '>= OK'
```
Trying to upload it:
```
Uploading chef-4298      [0.1.0]
ERROR: The data in your request was invalid
Response: Invalid value '>= BadVersion' for metadata.platforms
```

erchef error:

```
msg={ej_invalid,object_value,<<"metadata.platforms">>,<<">= BadVersion">>,string,string,<<"Invalid version constraint">>}; req_time=2
```

Perhaps this should go in another ticket?
