The currently approved trial of the development voting procedure! expects voting via forums. Agree that Helios might be preferable if it is not too much hassle to setup, but I wanted to follow the agreed-upon procedure…
EDIT: to clarify, I think we might consider other voting methods for future votes, changing method mid-voting is IMHO hugely undesirable unless someone makes the case this particular vote is too personal for voting on the forums. I am also honestly unsure whether anonymous voting is a good option for technical votes - in contrast to votes about people where the benefit is clear.
