The instinctive answer is yes...
BUT, in instances where the italic's design is much narrower than that of the roman, forcing the italic .tf to have the same width makes them awkwardly large and/or loosely spaced compared to the rest of the glyphs.
I'm curious to know your position. Do you sacrifice æsthetics for the sake of italic-roman compatibility? Or do you generally don't care and go for a more harmonious design?
Thanks in advance
