I think, occasionally, it's a lot easier to grok a command through googling than reading the built-in help. A fair amount of built-in *nix documentation I have run across is mediocre or unhelpful.
I often find that GNU man pages are heavy on explanation of options and light on purpose and practical usage (the latter is tucked away in info pages). That's not necessarily the wrong way to do manpages, but I much prefer OpenBSD-style manpages, which seem to be better at providing practical information.
Recursively searching through all files in the current folder (aka the normal use case for grep) is accomplished by using "grep -r". It's on line 270 in "man grep". And that assumes that you know what grep is at all. Would it have hurt so much to call grep "regexsearch" instead? Maybe -r could be the default?
Recursion is caused either by -R or -r on nearly all commands and is pretty standard, and r is virtually never the default on any command because that would be a bad idea. And yes, having to type regexsearch rather than grep would have been a bad idea; while grep isn't a great name it's far preferable to someone who types constantly. Search or find would have been better names, names need to be both short and descriptive on the command line, and short comes first.

"regexsearch" is more work to type and more space taken up everytime 'grep' appears in a command-line. And says nothing about recursion.
