Code review comment for ppa-dev-tools:fix-lp-credentials

For the das = get_das() stuff, that is ancient code that might be vestigial, or might still be needed. The change in this branch is commenting out the code (it currently does nothing, except trigger pylint/flake warnings) but is not relevant to these bug fixes, except just being in the way.

When I'm further along with feature development, it should be more obvious if this code is going to be needed (and should be cleaned up) or can just be deleted. But I'm leaving it as is for now.
