Re-instate the default tags and random/ramp soak interfaces
These were removed from the 2018 SP3 install kit as OSI found many customers removed these tags and interfaces after installation. However, our experience is the opposite and these tags are massively useful for diagnostic, experimental and training purposes.
I would suggest the option of installing them be re-instated into the PI Server install kit, with an explanation of why they are provided. If the customer does not want them, they can then uncheck the option.

@Kenneth Barber, Agreed, using the latest data collection technology would be best. Essentially I don't care how those tags get created or populated, so long as they are there by default. I have voted for your suggestion.

If these PI Interfaces were replaced with a single equivalent PI Connector or PI Adapter that communicates directly with the PI Data Archive, maybe I would agree with you. See the suggestion below:
https://feedback.osisoft.com/forums/555139-pi-connectors/suggestions/33282343-make-a-pi-signal-generator-connector-ramp-soakPI Interfaces have been superseded twice now. In my opinion, OSIsoft shouldn't force something that is both non-essential and outdated into install kits that every customer uses, even if the installation of the PI Interfaces is optional.
