Fire events in undamaged aircraft these days have been leaving plenty of time either for fire services to bring the fire under control and evacuate via steps, or for evacuation via slides in their absence
It's all working to plan and we don't have to worry about pax wandering about where they shouldn't.
In many outfits, this state of affairs will continue happily until another airframe is incinerated with pax inside, whereupon the SOPs will be revised.
In the interim, prospective pax deserve to know whether they are expected to remain seated for how long while the fire is doing its unpredictable thing.
Those who post a SOP that anything more than a brake fire (tested during certification) warrants an immediate evacuation might enjoy a well deserved marketing advantage
