Could we document the limitations?
I think it would not work for:

• adding or removing services
• changing a service's dependencies
• adding or removing instance level properties

Anything else?

[netroy]

adding or removing services

This can be addressed

changing a service's dependencies

This should work already.

adding or removing instance level properties

Yeah. states in services cannot be reloaded like this. That's a much trickier problem to solve.
