Honestly, I am a bit confused by the organization of the pre-conference this year. Recent Wikimanias allowed users to choose on site what to attend, be it Hackathon sessions, WMCON Follow-up days, or other workshops as long as there was still free space. Of course, sometimes this space is very limited or some formats even require limited access for having useful discussions (like https://wikimania2017.wikimedia.org/wiki/Wikimedia_Foundation_Learning_Days). Some of these limitations were published onwiki and helped me to decide in advance whether I want to commit myself to this very format for the full time or not. Personall,y I don't want to decide myself now what sessions could be most useful for me, which ones I should leave to other places when my expectations weren't met, which face-to-face chats will be more important than the sessions, etc.

Hence, will it be possible/allowed to switch between those formats which have not yet been marked as invite-only onwiki? Were you asking me for my preferences only for logistical reasons, size of rooms, etc?

Please help me understand why we need to register for pre-conference workshops for the first time. Thank you very much in advance! :-)
