Location and contents of robots.txt

Hi,
is it safe to allow everything in a robots.txt and the block rules in the .htaccess take care of the rest?
Speaking of a standard installation. (Of course you have to adjust your robots.txt, if you have other folders you don’t want to have crawled.)

User-agent: *
Allow: /

I’m asking, because maybe a small benefit would be, that there is no direct hint to a kirby installation this way.
P.s. If you want, you can even rename the panel folder and change your rewrite rules to the panel since kirby 2.2.0.
Securing the panel - good or bad practice? Post #9
