I think your most help wanted list/pop-up team is much more realistic
approach. Lets see if there is enough interest to actually make it happen.
What comes to our previous experience with Glance and moving to endorse
osc, I think I'm not alone stating that we can discuss this again after osc
has kept feature parity (and I mean to current release, not feature parity
2 years ago kind of thing) and actively addressed raised issues at least
for a couple of cycles. Obviously if you/your users wants to use it
meanwhile, that your call. If we cannot get that level of commitment, how
do we expect to support this long term?

I'm not willing to put our users through that misery again as it happened
last time as long as I'm core in this project.
