There is a Suggests: python3-dev.

This goes back to earlier days in cffi. Using the verifier requires -dev
at build time, but not runtime.

In the new out-of-line modes, runtime use will have the cffi-backend
package installed, so we can strengthen the dependency to Recommends or
Depends.

That said, you need -dev when building ABI-level extensions, but not
API-level ones. So maybe Recommends is the right thing to use...

Yes, I think for packages using ABI-level extensions should be
build-depending on -dev-all.

That shouldn't happen.

Packages using cffi should build extensions like that at build time, not
run time.

Tell me more about this python3-cryptography package you're using?

Package: python3-cffi
Version: 0.8.6-1
Severity: important

Installing python3-dev fixed this. Thus I conclude that there's a missing 
dependency here.

I verified that this still applies to the version in Unstable.

If that's true, then the build-depends should be python-dev-all, not just 
python-dev.
