Some do, though it’s extremely rare that I ever need to do so.
Audio clips on the same track may be joined to form a continuous track. If the clips are touching each other, you can just click on the common edge to join the clips.
Clips can also be joined by selecting the clips that you want to join and using the “Join” command (“Edit menu > Clip Boundaries > Join”). This also works for clips that are not touching (any gap between clips will be filled with silence).
