Sorry for the late reply here, guys. I really should be checking Discuss more. :P
The explanation I have right now is that what we're doing works for the time being. There's only confirmed two seasons for The Orville and its main characters. While going through each episode will yield long pages, this isn't exactly unheard of on Wikis that cover significant amounts of content.
The Memory Alpha wiki's page for Captain Picard is much bigger than anything we have on this Wiki yet and has over ten sections.
I do suppose when/if future seasons come around there can be discussions to manage pages more economically in order to better sustain the load of information. But that doesn't need to happen for at least the next couple years if not more. Our current practices in my opinion are fine.
