Yes. Disable is usually going to be fine if the service was in the
enabled state
since enabled will have stricter requirements.
A method as you suggest might be useful in some cases, but not all.
Well, I suppose for the problem I'm thinking of, it would also work.
The problem is:
the service is already enabled
an admin changes something in the config to an invalid value
I suppose a method to check that the configuration is enableable would
then just issue a no and give a diagnosis message. The concern in the
problem outlined is that currently a bad configuration could be setup and
it wouldn't be detected until a service refresh/restart
A method to validate property values might also be useful by itself.
