Good point Min. I also thought about it but looking at some of the existing APIs thought of keeping both.
For e.g. in deploy VM api there is a parameter called 'networkids' which can take an array of network IDs. Note that the naming convention of ending in 's'. Now by this logic we should name the parameter 'ids' and remove the existing parameter 'id' which will be a breaking change. In case the existing 'id' parameter is used for multiple IDs that breaks the parameter naming convention. I am all in favour of using the existing 'id' parameter if there is no issues with breaking the naming convention.
