I certainly didn't want to leave the impression that I consider the survey to be some sort of guarantee of priority from LWD: they've never operated that way, so I certainly don't expect it now.
The survey is an opportunity for us to say "these are the features we want", which LWD will then use as guidance to shape their plans. We know that they intend to develop features in parallel, and if calendars don't fit with other development plans, but they can get quick wins from other features, I fully expect those other features to come first. And that's fine by me. At some point the development cycle will come round to a time where our desire for calendars weighs together with staff availability and development costs, and calendars will be scheduled. The higher up the survey results calendars fall, the sooner that time will come, because LWD know that customer satisfaction matters.
"First on the survey" means nothing more than telling LWD "this is what we want, as soon as you can", and the lower down the survey it falls, the longer we are likely to have to wait, unless development conditions mean that calendars become a quick win in preference to other desirable features.
So, when I say "we have no-one to blame but ourselves", I mean it solely in terms of where calendars fall in the survey results, with "we" being the entire user base that completes the survey, which ultimately is only one factor in when calendars hit the development queue. But it's the one factor that we, the users, can influence by making ourselves heard.
