Then let me help enlighten you to our (or at least my) thought pattern.
The inherint argument is that BioWare can't live up to a fans own imagination. That is clear and understandable, a simple fact.
The real question in this discussion is, of what importance is Tali's face to us and in then end, of what importancy is that each individual is pleased.
First off, to draw the line to the comparision with other points such as showing or not showing other things like Palavan/etc.:
Tali as a character has emotional bonds with the player. If Palavan is an ugly planet by a fans standard, then it is an ugly planet. If Tali is ugly by a fans standard, then you just got a virtual relationship mutilated.
You see, each individual has unproportional more to lose if the face doesn't hit the preconceptions than if it were never shown. Furthermore, it is evident each individual has unique preferences. Even if BioWare manages to get a majority of the fans to accept the image, the rest WILL get disappointed, severity is individual. Some will like, some will hate it. That is as sure as you can get with human minds.
My intermediate proposal would be to show another quarian's face, at best a male face, so that there is still enough room for each individuals imagination for tweaking or personal retconning (reverse process of what I and Fenris are having right now in essentials

).
Actually, as opposed to my initial forthcoming, the end-discussion is not about each individuals pleasement, but about the rift between people who want to see her face and those who'd rather like to leave things to their personal favourite imagination.
The real question therefore would be who loses more.
If the face is not supplied, people that want Tali's face to get shown will not see her face. They will be upset to individual degrees, but at least still have their own imagination about how she might look, possibly with the context of another quarian's face as I proposed earlier (I do think a male quarian's face would indeed be the best suited choice, maybe even Reegar being the model to feature someone prominent).
However, if the face is revealed, everyone is facing (ironic use of words, I know) the consequences of his own preferences. Some might start squeeling on how BioWare "hit the spot", others might outright hate the concept. In every case, each single individual is set with the canon-concept that s/he'll not forget and which will continue to crumble the established imagination.
I think in the end the former choice would be the least worst option of said question, as it does not force anything upon an individual other than to keep on imagining. It is the logical choice.
But as I already stated, this is an emotional choice, and humans, especially if emotions are in the formula, are anything but logical, sometimes to our good, but foremostly to our bad.
I do not press anyone to accept my argumentation, I just hope I could clarify my (our) thinking.
Thank you
