When I wrote “man page/help of reclaim said it would not remove active installs” I should have written “man page/help said of/about reclaim it would not remove active installs”. I did not say ‘port help reclaim’ or man port-reclaim’. I used the main ‘man port’.
Where the flag is described ‘port help’ or 'man port' only says:
Reclaims disk space by uninstalling inactive ports and removing unneeded installation files.
It doesn’t mention that it removes anything but inactive ports. This is what made me not care about lists being presented. Beside, tThe list was huge, most of it py38 or p5 somethings. So, I trusted that statement (which turned out to be not completely true)
My suggestion would be to adapt the main port help.

And it says it will show you the list of everything it will uninstall before it does it. So you have an opportunity to cancel before it does that. I'm not sure how much more we can do to save the user from uninstalling things they didn't mean to uninstall. Do you have a suggestion?

If it does, use `sudo port setrequested` to tell MacPorts which ones you actually do want, as Daniel said. Conversely, look through the output of `port installed requested` and if anything is listed that you don't actually want, use `sudo port unsetrequested` to mark it as not needed.
