Comment (by arnolp):

 @peterwilsoncc thank you very much for your explanation, indeed.

 I was confused by a (bad) plugin, which was flushing rules on front end
 pages.
 Thus, calling :
 {{{#!php
 WP_Rewrite->flush_rules(true)
 --> /public/wp/wp-includes/class-wp-rewrite.php(1875):
 save_mod_rewrite_rules()
 --> /public/wp/wp-admin/includes/misc.php(278): file_exists('/.htaccess')
 <--- uses get_home_path() from front-end
 }}}


 (Well I could argue, if I was really in bad faith, that class-wp-rewrite
 is not in /wp-admin, thus "allowing" front-end use, but I really can't see
 a usecase of flushing rewrite rules on front end pages , seems to be a bad
 idea !)

 --> All good on my side. Not sure about the op's usecase, but that's a
 different one.

 correct value within the admin for WP in it's own directory:

 it was only ever designed to work within the admin. To modify it to work
 on the front-end as well would be considered an enhancement.

 desire to make it a front-end friendly function.
