There was no 'reaction' to Open that made Sandro give the second proposal. Sandro had always considered both as a part one and two..... and Sandro's proposals formed part of an investigation, seeking feedback from the user-base - not a fait accompli.
After the reaction to the Open only proposal in FF1, he reincarnated the Open play bonus proposal of March'16 in FF2. Then it went quiet.
Will has indicated that some of the proposals in FF1 are being considered. I'm interested to find out which ones make the cut.
The problem is, without Open you are left with the status quo and not actually making the feature stand out or be compelling.
