I wouldn't worry about using the tripod mount at a support strap attachment location, as this has been common for years. The main thing is to make sure the attachment is secure.
What I use is a Kirk strap with a Quick Release clamp that can then be mounted on either an Arca-Swiss style plate on the camera or the lens, depending on the lens/camera combination. If the lens has a foot, I mount it to the lens, otherwise to the camera (in my case, a L-bracket). The advantage is that when you are ready to mount on a tripod, you don't need to unscrew your strap.
This results in and least stress to the lens mount, and is very convenient.
