Mark, you can try it out by joining the Early Access Program. The PWS was provided for convenience only and can always be removed or replaced with a different web server. In the future IRIS will check if a local web server is present and can configure the instance during the installation to use that web server (IIS on Windows, Apache everywhere else). I am going to augment the primary post to include removal information. Hope this helps.

Enrico and I talked about this last year and he was able to verify that InterSystems addressed the issue, which will be available once we release the NoPWS adjustment.

I think that installing a web server is not more complex than installing and configuring VSCode. If an Apache (or IIS on Windows) instance is installed prior to the installation of InterSystems IRIS the IRIS installer will offer to configure that web server. From here on forward it is the same as before.
