On one hand many people don't want to be dead weight when the dice start rolling. On the other hand it can be more fun to be the Half-Ork Wizard with 7 INT trying to role play a big dumb guy who's only love is setting things on fire with his mind and getting paid for it.
There's the age old role play vs. roll play argument. With a good DM it shouldn't matter but if you're running some prebuilt campaign then it might lead to unexpected struggles.

At 7 int are you smart enough to even have learnt to cast cantrips?
I do think that there is a difference between playing a suboptimal combination and dumping your classes primary stats such that you're largely incapable of doing things...
There's a line between suboptimal and non-viable.
For example, a fighter which maxed charisma with appropriate feats for being admired/respected etc. Just a super stand up lovely guy. Super personable, gorgeous smile, good form, rarely seen him fight I admit - but he looks the part! But I do put some points in Str (Dex if finesse) and Con. Otherwise you probably can't actually be a fighter, you won't match the class descriptor (imo)
