Personally I really dont care what equipment a photo has been taken with, as long as the photo is worth looking at. There has been compelling, even iconic street work done with literally anything. Re good street work with telephoto lenses one name that comes to mind is DiCorcia, he made his famous book "Heads" with 400-600mm lenses (and remote studio lighting btw).
Telephotos will give that compressed look to your photos, typically used for portraits, and will inevitably lead you to portraity type results. Because if you try to shoot a scene with a tele and fit it all in, inevitably you will have to move back a few metres. By moving back perspective changes: say there's two people one in front of the other, you will not be able to tell who is actually closer to you just by looking at your photo. Things will look flat and compressed making it harder to convey to the viewer that sense of "being there". Its just a different aesthetic, more distanced, more remote. Just like every other photograhic tool and technique, that can be used as a means to visually communicate something. Do you want your photos to look like that? Use a tele. I dont, but others do and have produced interesting work, DiCorcia is only one of them. Its all about understanding how gear affects the final product, the photo, and making your choices accordingly.
