Actually a "keep bit depth" option when importing, is all that is
required. Importing integer audio files and converting them to floating
point never is needed, assuming that a DAW is able to use different
audio file formats at the same time. Only when recording floating point
is useful, at least if you want to continue mixing including the
recorded tracks.
