The default .htaccess blocks .well-known access

I use automatically generated SSL certificates for my site but they stopped working. It seems that the following lines of the Drupal .htaccess file blocks access to .well-known/acme-challenge/ which is needed for automatic domain validation.

  # Block access to "hidden" directories whose names begin with a period. This
  # includes directories used by version control systems such as Subversion or
  # Git to store control files. Files whose names begin with a period, as well
  # as the control files used by CVS, are protected by the FilesMatch directive
  # above.
  #
  # NOTE: This only works when mod_rewrite is loaded. Without mod_rewrite, it is
  # not possible to block access to entire directories from .htaccess, because
  # <DirectoryMatch> is not allowed here.
  #
  # If you do not have mod_rewrite installed, you should remove these
  # directories from your webroot or otherwise protect them from being
  # downloaded.

  RewriteRule "(^|/)\." - [F]

I have fixed it by adding the following RewriteCond

RewriteCond %{REQUEST_FILENAME} !.well-known/

This allows access to the .well_known folder bot denies all other dot-paths.

Others may be able to improve on my solution as I'm no Apache expert. It may be worth changing the install script to allow this access.
