Parameter sets

I believe this is a feature request, unless it's possible and I just don't see it.
Is support for planned, or would you consider supporting, Parameter Sets (eg. [PowerShell's Parameter sets](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_parameter_sets)) where if a Parameter that is exclusive to one set is present only completions that are valid in that set's context are valid and displayed.
