.htaccess in Perch folder

Hi,

I am doing some .htaccess rewrite rules on a website which affects using Perch when navigating around in admin.

To rectify I've simply created a .htaccess in the /perch/ folder with:

RewriteEngine Off

I assume this is fine to use and it won't affect how Perch works when navigating around the interface? Seems ok to me but thought I'd ask the question.
