InDesign 19
Steps: Opening any file with manually-built spot colors with the word "pantone" in their names brings up the "this document uses Pantone colors" blue nag
Expected: that spot colors built manually, not using any installed color books, will be left alone
Actual: apparently the software flags the word "pantone", regardless of its origin

Summary: Manually-created spot colors are being flagged in Indesign because they have Pantone in their names. I legally purchased Pantone books in prior years, and the colors I'm using were built by referring to the builds from those books. I am not using any installed software color libraries. I am not even using the color builds from the last several years' books. I may not use Pantone as a system anymore, but my printers do and pay their own licensing for its use. I have to tell them what color to use. How does Adobe propose I do this, if not in the way I have set up?
