I’m in complete agreement with you, but I’ll note that FOSDEM fails even your weaker test: I personally witnessed someone in a wheelchair being unable to access a talk because the room’s entrance (a curved staircase) couldn’t accommodate their chair. ULB is certainly a fun campus to have FOSDEM on (and I don’t have any real alternatives, given its size and location), but accessibility already seems to be relatively low on the list of concerns.
