It depends,
This service plays key role for storage profiles.
Lets say, you want to provision one VM and attache done particular storage profile to that VM & at the same time, if you restart the service, this is going to affect the VM provisioning. Also if there are already some VM where you have system defined or user defined storage profile attached, you may not be in the position to check whether VM is storage profile compliant during the service restart time frame But once it is restarted it should continue to work as expected. Overall, only features those are dependent on this profile service would be affected for small duration.
