Adding a template without a corridor is probably a linear template. There are potential drawbacks and it all boils down to whether you'll need more templates on that same alignment, and whether the technical aspects of the linear template will work for you.
First, from my own observations, it seems that once you place a linear template you won't be able to change the profile that it draws from. With a corridor, you can not only change the profile, you can also specify a non-active profile if you wish, and toggle them at will.
Second, if you need multiple template drops along a single element, you may also have parametric constraints, point controls, and external element attachments that will be common across them. In this case you'll benefit from having them all in one corridor element. It will also handle (for better or for worse) transitions automatically, and if you need to handle transitions manually, you can do that as well, and that will be better handled within a single corridor element.
Linear templates do have their own benefits, including being able to apply it in the reverse direction, etc. (This is something a corridor template drop should handle as well, but they don't.)
