There is undoubtedly a lot of work to make a great conference. I have hard
time imagine this could be ever done without a lot of time and effort on
the organizing side. I do not believe we can simply outsource a highly
technical conference to somebody outside of the community. LF is doing a
lot of great work to help with the venue and related stuff but content
wise it is still on the community IMHO.

My experience from the MM track involvement last few years is slightly
different. We have always had a higher demand than seats available
for the track. We have tried really hard to bring people who could
contribute the most requested topic into the room. We have also tried to
bring new contributors in. There are always compromises to be made but
my recollection is that discussions were usually very useful and moved
topics forward. The room size played an important role in that regard.

Yes, BPF track made the conference larger indeed. This might be problem
for funding but it didn't really cause much more work for tracks
organization (well for MM at least).

I do not have the same experience on the MM track. Even though the whole
community is hard to fit into the room, there tends to be a sufficient
mass to move a topic forward usually. Even if we cannot conclude many
topics there are usually many action items as an outcome.

This would be really unfortunate. LSFMMBPF has been the most attractive
conference for me exactly because of the size and cost/benefit. I do
realize we are growing and that should be somehow reflected in the
future. I do not have good answers how to do that yet unfortunately.
Maybe we really need to split the core agenda and topics which could be
discussed/presented on other conferences. Or collocate with another
conference but I have a feeling that we could cover more since LSFMMBPF
