Comment (by kcrisman):

 It looks like there is still no proper deprecation for the "old" piecewise
 stuff.  Given that there seems to be a significant amount of stuff that
 that has (even if in an antiquated form that should be redone), perhaps a
 potential solution would be to do a deprecation of `Piecewise` that leads
 to the old version, but where `piecewise` is the new one? (Wait, I already
 said this in comment:11.)  I agree with Volker that `piecewise_real` is
 probably too involved, but this is not so crucial a change that we
 shouldn't follow normal deprecation policy, especially since apparently
 people really do use the plotting and convolution/fourier stuff, buggy
 though it is.
