But it is being used for that purpose in *many* packages.
As an example, there are ~ 300 Python3 packages that have
"python3 (<< 3.7), python3 (>= 3.5~)" dependencies autogenerated using:
Depends: ${python3:Depends}
If this is considered a bug, then what is required is that dh-python adds
${python3:Breaks}, and then each of these packages has to be changed to:
Depends: ${python3:Depends}
Breaks: ${python3:Breaks}
