If you read the thread, you will see the claim: ”Info pages are older than man pages (the format dates back to ITS on the PDP-10).” - by a guy, going by the handle @amszmidt - so they’re both, from the same ‘limited era’, near enough.

Yes, all the time. The beauty of Unix style man pages, is they rely on the user(s) native $PAGER - so the search capabilities, are dependent upon what one chooses, for such - rather than the incredibly clunky, GNU thingy, that comes bundled with the info system, unfortunately…
Unix man pages, are also excellent - as they haven’t been deliberately crippled, in order to try and forcefeed us the info gruel… - in much the same way, that GNU Guile, was chosen as the “official” extension language, over TCL, for political reasons.
