Could you explain a bit more how is this a problem for python 3.8?

Buster version has:
  python3-rrdtool.install:
  usr/lib/python3*/dist-packages/rrdtool*[0-9]m-*.so

  rrdtool-dbg.install:
  usr/lib/python3*/dist-packages/rrdtool*[0-9]dm-*.so


After switching to automatic debug symbols with an extra python -dbg package:
  python3-rrdtool.install:
  usr/lib/python3*/dist-packages/rrdtool*[0-9]m-*.so

  python3-rrdtool-dbg.install:
  usr/lib/python3*/dist-packages/rrdtool*[0-9]dm-*.so

(This now generates a python3-rrdtool-dbg-dbgsym package)


But I fail to see how this helps with python 3.8. Are the .so name changed? 
How so?

I tried to look at your upload of twisted, but it looks like you forgot to 
push your changes, and twisted_18.9.0-4.dsc is not in the pool yet.
