By default, the <mapframe> is shown as a non-framed image, but very soon it will be shown inside of a small frame with an optional text caption at the bottom. Usually, frameless maps are good for insertion as part of some template, whereas framed images are good for insertion directly into the page, either by hand or by using Visual Editor. To insert a map without the frame, one has to add "frameless" attribute: <mapframe frameless .... To add a caption, use the text="..." attribute. Having text attribute automatically enables the frame.
If editors wish to preserve some templates from showing a frame, they should already add the frameless param without waiting for the deployment.
