Actually, there are many that are limited to only 5-10 submissions, not everyone has a lot of submissions -- submissions depend upon your ratings from that contest (and others)/percentage and newer members also don't have a lot of submission opportunities. There are also early access, best entry, submitting names for consideration of the market, and now likes are taken into consideration for some splits on some abandoned contests. So there are many perks and with each perk -- if you don't have access to them, they can also be seen as penalizations on the other side of the token. Also if you don't maintain certain percentages you also can lose your tier status which means inability to enter certain contests. With this being said, there is a lot more at stake than what you imply and these things at stake may not be obligatory or much important to you, but there are some here whom it does matter to, and quite a bit. So feedback, as I was meaning, to those that want to strive for these things, strive for at least trying to actually help the CH, or even both -- can be essential.
However, I digress, we all do what we can -- some more than others. We all also value different things -- some more than others. And I think taking all perspectives into view is important, because yes -- you can never please anyone. However, CHs should be the ones that are pleased and feedback, in my opinion, helps give direction, helps show interaction, and is a mandatory thing in real world brainstorming branding sessions and can be important here, as well, to ensure that the CHs are pleased.
