Support for older versions of Django

[RaimundoDiaz]

HI! I worked with this package for a project and it was really great all the time it saved me, now I am working on a different project that sadly has too old version of both Dango and DRF, even Python to be honest (Python ~2.7). So I was wondering if it would be too difficult to make support for older versions of Django and DRF. I've never tried to update or in this case make support for older versions of a package so I don't know if it is difficult. I really want to use this package on this project because the time it would save on creating the types would be insane.

django==1.8.19
djangorestframework==2.3.9

I also looked. for other options online because I thought that maybe there were similar packages for the same thing that supported older versions but I. didn't find anything.
