Double miss - no replacement for Wordpad
Wordpad didn't just add some formatting, it was the only Microsoft editor that could actually generate RTF that complies with the RTF spec, and as such had application in some niches of the ecosystem where RTF is (was?) still being used. But today's Microsoft is not the Microsoft of old that cherishes backwards-compatibility and 'developers, developers, developers'.
Notepad++ is ok, I guess. But I don't use it often enough to remember the shortcuts and plugins for the ++ features, like validating and pretty-printing JSON and XML (also still in use).
Keeping wordpad and notepad as they were was a totally valid option, especially as MS' notepad++ competitor is VS code. I guess someone picked it up as a project to survive the next round of redundancies, being able to say "I'm a maintainer of a core application in the OS"?
