Analysis widget - hoping for enabled = false support and Category support

[DougBrowning]

I am seeing that hiding params using self.params[3].enabled = False works great as a regular toolbox but when I publish the tool as a service in both Pro and ExB this does not work and it just always shows the param.

def updateParameters(self):

if(self.params[2].value):
self.params[3].enabled = True
else:
self.params[3].enabled = False
return

Is this a known issue?  I am seeing a number of things that work in a toolbox but not as a service.

Another example is Category is not supported in ExB but does work in Pro.  This is making it hard to create a consistent user experience.

Is there any doc on what is and is not supported when publishing?

thanks a lot
