I know we talked about it. Wonder if it was done when we were going through the initial design and no one had played in far enough to notice. 'Tis a strange thing. Good to know.
Is it a serious issue? Doesn't seem like much to me but this is not my area of knowledge. FatR you mention in Juan's Mods it doesn't really matter much. How does the overall speed number impact A-t-A?
After playing BB Enhanced against ny59giants, I don't believe the 15-20 knots speed bonus is decisive. In terms of overall plane losses we broke even by the end of the game in October of 1942. In terms of being able to protect their bases and threaten Japanese ones, Allies achieved rough parity in late summer and superiority by the end of September. And I know now, it was possible to do better in that game.
In our current 2x2 game of CV Enhanced Allied aviation is getting stomped, of course. But actions like sending 3-6 fighters on CAP over the city that gets swept by 60+ Japanese fighters every day for more than a week might just have more to do with it, than plane stats.
And, as I mentioned before, I didn't even notice the bonus in this game, before being pointed to it. Certainly, initial air campaigns were heavier than anything I've experienced in AE before (congtatulations to Yubari). Mostly on bombers, but fighter units didn't get away unharmed as well. Both Tainan Ku and Yamada Ku were hit pretty hard, and the former only recovered after getting an infusion of pilots from reserve and getting some experience by shooting Dutch around Loemadjang.
John, you have played several games of Scen 70, at least in initial months, so you should have more data about this than me.
It should be noted, that if Zero, Oscar and Frank get a speed buff, this indeed looks like a correction created by the discussion of their stock stats selling them short.
EDIT: And for the illustration here's the decisive first combat of April 10 from my game against Yubari, the only one where sweepers were significantly outnumbered (in the second sweep of the day Japanese met nearly equal numbers already, and over the day there was 153 sweeping planes vs. 130-something CAP flights).

So, 85 Allied planes (64 airborne at the beginning of battle), including 17 obsolete ones, vs 44 Zeros, with the latter benefitting from the sweep bonus.
Here's the Japanese unit involved, after losing 7 pilots in the combat above:
Fatigue on April 10 was minimal and I even sent some of the fatigued/least experienced pilots to the group reserve by hand for that day. So, I do believe, that given the conditions (and luck that caused the biggest and the most experienced Kokutai to go in first) the results were quite reasonable and the speed changes do not have a major effect on the gameplay.
