That will be a good topic worthy to discuss to open the eyes of the community.
my reply would be
separate teams have separate software that all have their own proposals platform (suggestion box)
then the community(not one team) then poke at the suggestions and improve on them until all teams can agree on one master proposal
then when it comes to a fair agreement/compromise on a fair acceptance. each team then release a version of their software..
lets call it a B version. which thee community can download that includes the master proposal
EG core have version 0.17a which would be the normal version of current active rules. and then a 0.17b that includes the master proposal the community has should high agreement of
where the other teams also have a version B of the same master proposal
then if all the brands version B's show high activation.. then cores next 0.18a(active rules) would the activated master proposal
if the master proposal doesnt get consensus. the its just not activated... and cores 0.18a wont have the master in it. but atleast each team would get to offer the CHOICE without any brand control fights
that way its not a you need to download only cores latest version or get kicked off the network. but people can download other teams too.. and where the proposal is a separate thing.. thus its not a brand debate. but a consensus debate because the proposals are not forced by any single brand as they are offered by all brands (as version b) while also letting users not be forced into it by them also having the currently active consensus version(a) available to 'no vote'
that way its actually consensus opt-in while having freedom to choose a brand..rather than a follow one team or else
