Actually, I do, given an ideal encoding system without any compatibility compromises. I think that the presence of the separate final and medial sigma codepoints, and especially of the separate lunate sigma symbol, will become a substantial normalization problem for Greek text. Too many people creating Greek texts will use only the lunate sigma for both medial and final, while the majority use the final for a terminal sigma and the medial for a non-terminal sigma. So either there should only be one sigma, with the presentation being determined by position (unless the font defines both positions as lunate), or there should only be the medial and terminal and no lunate "symbol," with lunate being defined only by the font - but then most people entering Greek text would just use the medial form for all sigmas, regardless of the position. Maybe text entry could correct this . . .
I like to think of the long s as similar to the final sigma. Nobody thinks that final sigma should be a presentation form of sigma.
But this opinion is pretty late in the game, isn't it? I just can't wait for all the search failures resulting from searching for τις in a text with τιϲ
