When denying access, let the admin determine whether to send an email to the user
Today when a user wants access to a resource, the admin receives an email with their request. If the admin then denies the user's request, the user is sent an email from SharePoint. As an admin, I like to send my own email stating why, and maybe where to go instead. Or I may structure permissions differently than what would happen if I just clicked "Accept". So I don't want SharePoint to automatically send this email. How about a checkmark I can uncheck when I deny the permissions? Admins need this level of control to prevent a confusing user experience!

Simple workaround: Put your explanation into the comments box before denying.
We'd love to make a customized message telling them to contact the site owner to be added into the correct AD/Exchange group.

Totally agree. It's really annoying to users to get emails that contain insufficient information (such as why one's access request was denied, or don't give them details on what level of access they've been given).
